What Is the Nelson-Denny Reading Test?
The Nelson-Denny Reading Test, commonly abbreviated NDRT, is a standardized assessment of silent reading ability.
It measures vocabulary, reading comprehension, and reading rate in high school and college students. Schools and other organizations may use the results to evaluate general reading proficiency, support course placement, identify students who may need additional assistance, or measure progress following instruction.
The assessment is not normally purchased or scheduled directly by an individual test taker. It is selected and administered by a school, college, training program, employer, testing office, or other qualified organization.
Key point: The Nelson-Denny is primarily an educational reading assessment. It is not one centrally administered admissions exam with a single national registration process, fee, passing score, or retake policy.
Current Forms I and J
The current edition contains two parallel forms identified as Form I and Form J.
The forms have been equated so that they can be used interchangeably. An institution may use one form for an initial assessment and the other for a later assessment of reading progress.
Form I
One complete version of the Vocabulary and Comprehension assessment.
Form J
A parallel version designed to measure the same reading abilities at a comparable level.
Older Nelson-Denny information may describe Forms G and H. Those forms should not automatically be treated as the format you will receive. Ask the administering organization which form and timing rules it currently uses.
Nelson-Denny Test Structure
The current assessment includes two core subtests and an optional Reading Rate measure.
Vocabulary
Vocabulary questions present an opening statement followed by five answer choices. The test taker selects the word or phrase that best completes the statement.
Questions measure word knowledge and the ability to recognize precise relationships between words and ideas.
Comprehension
The current Comprehension subtest includes seven passages drawn from academic subject areas such as the humanities, science, and social science.
The passages are followed by 36 multiple-choice questions. Each question contains five answer choices.
Reading Rate
Reading Rate is an optional supplemental measure taken during the Comprehension subtest.
After exactly one minute, test takers record the number corresponding to the last sentence they were reading in the first passage. They then continue the Comprehension subtest.
How Long Is the Nelson-Denny Reading Test?
The published administration range for the current Forms I and J is approximately 35 to 56 minutes.
The exact time used for your assessment depends on the administration selected by the institution. The administering organization may use standard timing, an available extended-time administration, or an approved accommodation.
Standard Administration
Uses the timing and instructions selected by the administering institution for the standard assessment.
Extended Administration
May provide additional time when the institution uses the published extended-time option or an approved accommodation.
Follow the timing directions given by your test administrator rather than assuming that timing listed for an older Nelson-Denny form applies to your assessment.
Vocabulary Questions
The Vocabulary subtest measures knowledge of words commonly encountered in high school and college-level academic material.
Items are presented in a sentence-completion format. You must identify the answer that forms the most accurate and logical relationship with the opening statement.
Vocabulary Skills to Review
- Synonyms and closely related meanings
- Antonyms and contrasting meanings
- Word relationships and associations
- Academic vocabulary
- Precise differences between similar words
- Common roots, prefixes, and suffixes
- Using sentence meaning to eliminate unsuitable answers
Vocabulary Strategy
- Read the complete opening statement before looking at the answer choices.
- Predict the type of word or relationship that would complete the statement.
- Eliminate choices that do not fit grammatically or logically.
- Use roots, prefixes, and suffixes when a word is unfamiliar.
- Choose the most precise answer rather than one that is only loosely related.
- Keep moving because the assessment is designed to measure performance under time limits.
Reading Comprehension Questions
The Comprehension subtest measures how well you understand and interpret academic passages.
Questions may require you to locate explicitly stated information or draw a conclusion supported by the passage.
Direct Understanding
- Main ideas
- Supporting details
- Sequence of information
- Definitions in context
- Cause-and-effect relationships
Interpretation
- Reasonable inferences
- Author purpose
- Tone and viewpoint
- Organization and structure
- Conclusions supported by evidence
Comprehension Strategy
- Read at a steady pace rather than attempting to memorize every sentence.
- Identify the main point of each paragraph.
- Notice transition words that signal contrast, cause, sequence, or conclusion.
- Return to the passage when a question asks about a specific detail.
- Base answers on the passage rather than on outside knowledge.
- Reject answers that make claims stronger or broader than the passage supports.
How Is Reading Rate Measured?
Reading Rate is an optional measure collected during the first passage of the Comprehension subtest.
Test takers begin reading at their normal pace. After one minute, the administrator signals them to record the number associated with the last sentence they were reading. They then continue the Comprehension section.
Reading Rate should not be treated as a race. Read at a controlled pace that allows you to understand the passage. Extremely fast reading is not useful when comprehension declines.
How Is the Nelson-Denny Scored?
Vocabulary and Comprehension responses are first scored according to the number of correct answers.
The current scoring system can report several types of results. The exact information you receive depends on the reports selected by the administering institution.
Index Scores
Standardized scores with an average of 100 and a standard deviation of 15.
Percentile Ranks
Comparisons showing the percentage of people in the applicable normative group who scored at or below the test taker.
Age and Grade Equivalents
Comparisons describing performance in relation to the age-based or grade-based normative sample.
General Reading Ability
A composite created from the Vocabulary and Comprehension index scores to provide a broader measure of overall reading ability.
Grade-equivalent scores are comparisons, not literal course-placement decisions. A school should interpret the complete score report together with the student’s educational history and the purpose of the assessment.
What Score Do I Need?
The test publisher does not establish one universal passing score for every institution and purpose.
A school, employer, training program, or admissions office may establish its own required score, percentile, index score, grade equivalent, or placement rule.
Before testing, ask the administering organization:
- Which Nelson-Denny score will be considered?
- Is there a required minimum or recommended range?
- Will Vocabulary and Comprehension be reviewed separately?
- Will the General Reading Ability composite be used?
- How will the result affect placement, admission, employment, or remediation?
How Do I Register?
Individuals generally do not register for the Nelson-Denny through one national testing website.
Contact the school, college, academy, employer, training program, testing center, or other organization requiring the assessment.
Questions to Ask the Administrator
- Which form of the Nelson-Denny will I take?
- Will the assessment be administered on paper or online?
- What date, time, and location are available?
- Is there a testing or administrative fee?
- What identification or paperwork must I bring?
- What timing option will be used?
- How do I request an accommodation?
- When and how will I receive my results?
Paper and Online Administration
The current assessment can be administered individually or to a group. Depending on the materials and system used by the institution, responses may be collected on paper or through an online administration system.
Paper Administration
- Uses a secure test booklet
- Uses an approved answer sheet
- May be given individually or to a group
- Results may be scored manually or entered into the scoring system
Online Administration
- Uses a secure institutional system
- Presents the assessment on a computer
- Calculates subtest and composite results
- Generates reports selected by the administrator
How Much Does the Test Cost?
There is no universal examinee fee for the Nelson-Denny Reading Test.
Some schools include the assessment in tuition, admissions, placement, or student-service costs. Other organizations may charge a local testing or administrative fee.
Ask the institution whether payment is required and whether the fee is refundable if you cancel or miss the appointment.
What Should I Expect on Test Day?
Test-Day Checklist
- Confirm the appointment time and location.
- Bring the identification requested by the administrator.
- Arrive early enough to complete check-in.
- Follow instructions about pencils, personal belongings, phones, and watches.
- Listen carefully to the directions for each subtest.
- Read at your normal controlled pace during the Reading Rate measurement.
- Work steadily because the assessment is timed.
- Do not copy, photograph, discuss, or reproduce secure test material.
When Will I Receive My Results?
Result timing depends on the administering institution and the scoring method it uses.
Online scoring can calculate and generate reports quickly, but a school or organization may review the results before releasing them to the test taker.
Ask the administrator:
- Whether you will receive a complete score report
- Whether results will be provided online, by email, by mail, or in person
- When results are expected
- Who can explain the score report
- Whether scores will automatically be sent to another department or organization
Can I Retake the Nelson-Denny?
There is no universal publisher rule stating that every test taker may or may not retake the Nelson-Denny.
The institution administering the assessment determines whether retesting is allowed, how long a test taker must wait, and which form will be used.
Because Forms I and J are parallel, an institution may use the alternate form when reassessing reading ability or measuring progress.
The old claim that every test taker must permanently keep the score from the first attempt is not a general Nelson-Denny rule. Retesting decisions belong to the school or organization using the assessment.
How Can I Prepare?
Preparation should focus on vocabulary knowledge, reading comprehension, and efficient reading under timed conditions.
Begin with an untimed practice set so that you can identify weak skills. Add stricter timing after you understand the question formats and can answer accurately.
