Reevaluation and re-evaluation have the same basic meaning, but their spelling can make writers pause. Is the hyphen necessary? Is one form considered wrong? And which version should you use in an academic paper, business report, website, or everyday sentence?
The short answer is that both forms are established in English, but usage varies by dictionary and editorial style. Cambridge lists re-evaluation as its headword while explicitly giving reevaluation as an alternative, so the choice is not as simple as “one is correct and the other is incorrect.”
For most writers, the practical issue is consistency and context. This guide explains what reevaluation means, why the hyphen appears, when each spelling makes sense, how related forms such as reevaluate work, and what to do when a style guide gives you a specific preference. By the end, you will have a simple rule for choosing confidently.
Reevaluation vs. Re-evaluation: What Is the Correct Spelling?
Both “reevaluation” and “re-evaluation” are used correctly in modern English. The difference is the hyphen, not the underlying meaning.
Cambridge Dictionary gives re-evaluation as the main dictionary entry and identifies reevaluation as another form. Its definition describes the word as the process of judging or calculating the quality, importance, amount, or value of something again.
So, if you write:
The new evidence led to a reevaluation of the original conclusion.
or:
The new evidence led to a re-evaluation of the original conclusion.
The intended meaning is essentially the same.
Is “Reevaluation” a Word?
Yes. Reevaluation is a standard English word formed from re- and evaluation. It means another evaluation or a process of evaluating something again.
The same pattern appears in other English words, including reevaluate, reevaluated, and reevaluating. Cambridge likewise recognizes both reevaluate and re-evaluate.
Is “Re-evaluation” Also Correct?
Yes. Re-evaluation is also an established spelling.
The important point is not to treat the hyphenated form as a spelling mistake merely because another dictionary or publication prefers the closed form. English hyphenation often varies between sources.
Do They Mean the Same Thing?
In ordinary usage, yes.
Both forms describe looking at an earlier judgment, estimate, decision, or assessment again. The second evaluation may confirm the original conclusion, modify it, or replace it.
For example:
- The committee ordered a reevaluation of the proposal.
- The committee ordered a re-evaluation of the proposal.
There is no meaningful difference in the action being described.

Quick Rule to Remember
If you need a simple working rule, remember this:
Use the spelling required by your dictionary, publication, or style guide. If no specific rule applies, choose one accepted form and use it consistently.
For general writing, reevaluation is a perfectly valid choice. At the same time, re-evaluation should not automatically be marked wrong.
What Does “Reevaluation” Mean?
Reevaluation means the act or process of evaluating something again.
The original evaluation might have happened earlier, but new information, changing circumstances, or a need for greater accuracy creates a reason to examine the matter again.
For example:
- A company may conduct a reevaluation of its business strategy after sales decline.
- A researcher may perform a reevaluation of previous findings after discovering new evidence.
- A teacher may request a reevaluation of a student’s work if an error was found in the original grading.
- An organization may undertake a reevaluation of its priorities after major changes in its environment.
Cambridge also uses the word in medical, academic, business, and research contexts, demonstrating how broad its application is.
Reevaluation as a Noun
Reevaluation is a noun.
Its common structure is:
reevaluation + of + thing being reconsidered
Examples:
- reevaluation of the evidence
- reevaluation of the policy
- reevaluation of the estimate
- reevaluation of the results
- reevaluation of the strategy
You can also use it with possessives:
The committee’s reevaluation of the proposal changed the final recommendation.
Related Words: Reevaluate, Reevaluated, and Reevaluating
The noun belongs to a small family of related forms:
| Word | Part of speech | Example |
| reevaluate | Verb | We need to reevaluate the proposal. |
| reevaluated | Past tense/past participle | The committee reevaluated the evidence. |
| reevaluating | Present participle/gerund | They are reevaluating the policy. |
| reevaluation | Noun | The reevaluation produced a different conclusion. |
| reevaluations | Plural noun | Several reevaluations were conducted. |
The hyphenated alternatives—re-evaluate, re-evaluated, re-evaluating, and re-evaluation—can also be encountered.
Why Is “Reevaluation” Usually Written Without a Hyphen?
The reason is broader than this single word.
English commonly combines prefixes with base words to create closed words. Re- is a productive prefix that often means “again” or “back.” As combinations become familiar, they are frequently written as single words.
Chicago’s hyphenation guidance notes that compounds formed with prefixes are usually closed, while also recognizing that hyphens can improve legibility in particular situations.
That explains why you cannot reliably decide hyphenation simply by looking at the prefix.
The Prefix “Re-” and Its Meaning
In reevaluation, re- contributes the idea of doing something again:
re- + evaluation → reevaluation
Similarly:
- re + assess → reassess
- re + consider → reconsider
- re + inspect → reinspect
- re + examine → reexamine
The spelling conventions of individual words are not always identical, however.
Why the Double “E” Looks Unusual
This is probably the biggest visual reason writers hesitate over reevaluation.
The word begins:
r-e-e-v-a-l-u-a-t-i-o-n
Those two consecutive e letters can look strange, especially when you are accustomed to seeing a hyphen after re-.
But a visually unusual sequence is not automatically an error. English contains many words with consecutive vowels, and the absence of a hyphen does not mean the word is incorrectly formed.
Why English Does Not Hyphenate Every “Re-” Word
If every prefix combination were automatically hyphenated, English would become unnecessarily cluttered.
Compare:
- reconsider
- reassess
- reassign
- reenter
- reexamine
- reevaluate
Some writers may instinctively add a hyphen to make the structure easier to see, but established spelling conventions do not require a hyphen simply because the prefix is recognizable.
When Should “Re-evaluation” Be Hyphenated?
The most useful way to approach this question is not to search for a universal “always hyphenate” rule.
Instead, consider three factors:
- Your dictionary
- Your style guide
- Readability
Chicago explains that prefixes are normally closed but says hyphens can sometimes make compounds more legible. Its guidance specifically notes retaining a hyphen to prevent certain doubled letters and using hyphens in other cases where they improve clarity.
When the Hyphen Helps Readers Parse the Word
A hyphen can visually separate re- from the base word:
re-evaluation
That can make the word’s construction immediately obvious to some readers.
However, readability is a reason to consider a hyphen—not proof that the hyphen is mandatory.
When a Dictionary or Style Guide Prefers the Hyphen
This is one of the strongest reasons to use re-evaluation.
If your university, employer, publisher, journal, or client follows a particular style guide, that instruction takes priority over personal preference.
A professional editor is not usually trying to decide which spelling “looks better.” The goal is to make the document consistent with its governing style.
In Specialized or Technical Writing
Technical publications often develop their own conventions.
A medical journal, legal publisher, academic department, or company may have an editorial style that differs from the conventions used by a general dictionary.
In that situation, follow the publication’s rules rather than changing terminology based on personal preference.
When Should You Use “Reevaluation” Without the Hyphen?
Use reevaluation when it is the accepted form in the style system you are following.
It works naturally in:
- general articles
- business documents
- academic prose
- reports
- educational material
- websites
- professional correspondence
For example:
The committee recommended a reevaluation of the current policy.
New evidence prompted a reevaluation of the study’s conclusions.
The company began a reevaluation of its long-term strategy.
The closed form is also useful when you want to avoid unnecessary visual punctuation. Chicago’s general guidance favors closing prefix compounds unless a hyphen serves a genuine purpose.
Examples With “Reevaluation”
Academic:
The discovery prompted a reevaluation of the study’s original assumptions.
Business:
Falling demand forced the company to undertake a reevaluation of its pricing strategy.
Education:
The teacher requested a reevaluation of the student’s examination results.
General writing:
The experience led to a reevaluation of his earlier decision.
None of these sentences requires a different meaning simply because the hyphen is absent.
Examples With “Re-evaluation”
The same sentences can use the alternative spelling:
The discovery prompted a re-evaluation of the study’s original assumptions.
Falling demand forced the company to undertake a re-evaluation of its pricing strategy.
The difference remains orthographic, not semantic.
Reevaluation vs. Re-evaluation in Different Types of Writing
The “best” spelling can depend on where your writing will appear.
| Writing context | Recommended approach | Why |
| Academic assignment | Follow your required style guide | Institutions may specify editorial conventions |
| Journal article | Follow journal instructions | Publishers often maintain house styles |
| Business report | Follow company style | Consistency matters across documents |
| General website | Use an accepted modern form consistently | Reader clarity is the priority |
| Personal writing | Either established form | No special style may apply |
| Technical publication | Follow field/publisher terminology | Specialized conventions can differ |
Academic and Research Writing
Academic writers should avoid treating spelling preference as a matter of personal taste when a formal style has already been specified.
If your institution requires a particular manual, check that manual. The same principle applies when submitting to a journal: the journal’s author guidelines outrank your preferred spelling.
This matters because editors assess consistency across an entire manuscript. A document that alternates randomly between reevaluation and re-evaluation can look poorly edited even though both forms are recognized.
Business and Professional Writing
Business writing benefits from a simple rule: pick the house style and stick to it.
Imagine a company report that uses reevaluation on page 2, re-evaluation on page 14, and re-evaluate elsewhere without any editorial reason. The problem is not that one sentence suddenly becomes grammatically wrong. The problem is inconsistency.
A professional document should feel deliberate.
Medical and Technical Writing
Technical writers have an additional responsibility: terminological consistency.
A medical or scientific publication may use a particular spelling throughout thousands of words. In such environments, changing established terminology because another dictionary uses a different form can create unnecessary editorial work.
Always check the publication’s instructions before making a manuscript-wide change.
Websites, Blogs, and SEO Content
For online content, writers sometimes worry that they need to use both reevaluation and re-evaluation repeatedly because users may search for either.
That is usually a poor editorial strategy.
Write naturally. If both variants are relevant to the topic, mentioning the alternative once—such as in the opening explanation—can satisfy the spelling question without making the article awkward.
SEO should support clarity, not dictate unnatural spelling choices.
Reevaluation vs. Re-evaluation in American and British English
It is tempting to label one form “American” and the other “British,” but that would oversimplify the issue.
Cambridge’s dictionary entries show re-evaluation with reevaluation as an alternative in both its UK and US presentations.
That means the distinction cannot be reduced to a simple geographical rule.
| Question | Practical answer |
| Is the hyphen exclusively British? | No. |
| Is the closed form exclusively American? | No. |
| Can both appear in published English? | Yes. |
| Does regional English influence style? | Sometimes. |
| What matters most in formal writing? | The applicable style guide and consistency. |
Why Regional Style Does Not Always Decide the Spelling
English spelling conventions overlap across countries. Dictionaries may make different editorial decisions, and individual publishers may establish their own preferences.
Therefore, avoid rules such as:
“British English always uses the hyphen.”
or:
“American English never uses the hyphen.”
Those statements are too absolute.
Common Mistakes With “Reevaluation” and “Re-evaluation”
Treating the Hyphen as Mandatory
Mistake: Assuming reevaluation must be incorrect because re- and evaluation are separate meaningful elements.
Better approach: Recognize that English frequently closes prefix combinations.
Treating the Hyphen as Always Wrong
The opposite mistake is equally unhelpful.
If a dictionary or publication uses re-evaluation, changing every instance to reevaluation without checking the applicable style can create an editorial inconsistency.
Changing the Spelling Mid-Article
This is especially common when a writer edits one section manually.
Better practice: Decide on the preferred form early, then search the finished document for the alternative spelling before publication.
Confusing “Reevaluate” With “Re-evaluate”
The same issue appears in the verb:
We need to reevaluate the proposal.
and:
We need to re-evaluate the proposal.
Cambridge recognizes both forms.
Do not assume that because you selected reevaluation, every style source must also use reevaluate. Check the relevant authority.
Assuming Two Consecutive Vowels Require a Hyphen
This is a useful misconception to eliminate.
The sequence ee may look unusual, but English spelling is not governed by a rule saying that two vowels must be separated with a hyphen.
The correct spelling depends on the established word form and the applicable editorial convention.
Reevaluation vs. Re-evaluation: Sentence Examples
Examples in Everyday Writing
Reevaluation:
After hearing both sides, she decided that the situation required a reevaluation.
Re-evaluation:
After hearing both sides, she decided that the situation required a re-evaluation.
Both sentences communicate the same basic idea.
Examples in Academic Writing
The researchers conducted a reevaluation of the original data after identifying a methodological limitation.
The evidence supports a re-evaluation of the earlier interpretation.
The key noun remains the same in meaning: an evaluation performed again.
Examples in Business Writing
Rising costs prompted a reevaluation of the company’s operating model.
The board requested a re-evaluation of the proposed investment.
Here, the choice should normally follow the company’s established editorial style.
Examples in Formal or Professional Writing
The evidence warrants a reevaluation of the previous recommendation.
The circumstances justify a re-evaluation of the current procedure.
Again, the hyphen does not fundamentally change what the sentence means.
Incorrect or Awkward Examples
Incorrect construction:
The committee conducted a reevaluation again.
This is not necessarily grammatically impossible, but again is often redundant because re- already communicates the idea of doing something again.
Better:
The committee conducted a reevaluation.
Another awkward construction:
The committee did a re-evaluation.
Here, the word has been split incorrectly. If you use the hyphenated form, write re-evaluation, not re-evaluation.
How to Decide Which Spelling to Use
When you encounter the word during editing, use this short decision process.
Step 1: Check Whether Your Style Guide Specifies a Form
If your university, employer, journal, or publisher provides a style guide, follow it first.
Step 2: Check a Reliable Dictionary
If no house style exists, consult a reputable dictionary rather than relying on spellcheck alone.
This is particularly useful because dictionaries can identify alternative spellings that automated grammar tools may not explain.
Step 3: Prefer Consistency
Once you have chosen an accepted form, use it consistently.
For example, do not casually alternate between:
- reevaluation
- re-evaluation
- re evaluation
The last form is not an appropriate third variant.
Step 4: Choose Readability When No Rule Applies
If no external authority dictates the spelling, consider what will be easiest for your audience to read while remaining within established usage.
Editor’s tip: Hyphenation decisions are often less about “right versus wrong” and more about standard usage, house style, and reader clarity.
Reevaluation, Reassessment, and Reexamination: Are They the Same?
These words overlap, but they are not always interchangeable.
Reevaluation vs. Reassessment
Reassessment usually emphasizes making another assessment, often because circumstances or evidence have changed.
Cambridge defines reassessment as a second or further assessment, particularly when the goal is to decide whether an earlier judgment or decision should change.
For example:
The new safety data prompted a reassessment of the risks.
Reevaluation can be broader and can refer to reconsidering value, quality, importance, amount, or another evaluative judgment.
Reevaluation vs. Reexamination
Reexamination emphasizes looking at something carefully again.
For example:
The discovery led to a reexamination of the evidence.
Cambridge recognizes both re-examination and reexamination, again demonstrating that English hyphenation can vary even among closely related words.
Reevaluation vs. Review
Review is broader.
A review might involve summarizing, checking, inspecting, or considering something. A reevaluation specifically emphasizes evaluating it again.
Choosing the more precise word can make professional writing stronger.
A Practical Decision Guide
| If you are writing… | What to do |
| A university assignment | Check the required style |
| A journal manuscript | Follow the journal’s author guidelines |
| A company document | Follow house style |
| A general article | Use either established form consistently |
| A website | Prioritize natural, readable language |
| A document with no style requirements | Choose a reputable dictionary-supported form |
| A document already using one form consistently | Usually keep that form |
The important lesson is that hyphenation is an editorial decision governed by context, not a test of whether you understand the meaning of the word.
Conclusion
Reevaluation and re-evaluation are both established spellings, so the hyphen does not turn a correct word into an incorrect one. The real issue is which editorial convention you are following. Cambridge recognizes both forms, while Chicago explains that prefix compounds are generally closed but that hyphens can sometimes improve readability or resolve specific spelling issues.
If you are writing without a prescribed style, reevaluation is a straightforward modern choice. If your publisher, institution, or organization prefers re-evaluation, use that form instead. Most importantly, avoid switching between the two randomly.
One final actionable tip: before submitting an important document, check your style guide and run a consistency search for both spellings. A common mistake to avoid is assuming that a hyphenated variant is automatically more grammatically correct. In professional writing, deliberate consistency matters more than personal preference.
Frequently Asked Questions
Q1. Is “reevaluation” or “re-evaluation” correct?
Both spellings are established. Cambridge lists re-evaluation as its entry and identifies reevaluation as an alternative. The choice therefore depends on the dictionary, publisher, or style guide you are following. If no authority specifies one, choose an accepted form and use it consistently.
Q2. Is “reevaluation” one word or two?
Reevaluation is one word, with no space between re- and evaluation. The alternative spelling uses a hyphen, as in re-evaluation. Writing re-evaluation as two separate words is not the standard form of this noun.
Q3. Is “re-evaluation” grammatically correct?
Yes. Re-evaluation is a legitimate hyphenated spelling. It is not grammatically incorrect simply because another source prefers reevaluation. Cambridge uses re-evaluation as its headword and lists the closed form as an alternative.
Q4. Does the hyphen change the meaning of reevaluation?
Normally, no. The hyphen primarily changes the visual spelling. Both reevaluation and re-evaluation refer to evaluating something again. In ordinary prose, readers will understand the two forms as equivalent in meaning.
Q5. Is “reevaluate” or “re-evaluate” correct?
Both forms are used. Cambridge lists re-evaluate and identifies reevaluate as an alternative. For formal writing, follow the style guide or dictionary relevant to your audience rather than assuming one form is universally mandatory.
