STRUCTURE BY LEVEL
A Closer Look: ISEE Structure by Level
The ISEE varies by level. Explore the breakdown for each test tier.
- Verbal Reasoning: Synonyms & sentence completions (34–40 questions, 20 min)
- Quantitative Reasoning: Word problems & math reasoning (37–38 questions, 35 min)
- Reading Comprehension: 5–6 passages, 36 questions, 35 min
- Mathematics Achievement: Math skills & computation (47–50 questions, 40 min)
- Essay: 1 prompt, 30 min (unscored, sent to schools)
Note: Question counts and timing vary slightly by level.
- Auditory Comprehension: (Grade 2 only)
- Reading & Math: Multiple choice, grade-appropriate
- Writing Sample: Picture prompt (unscored, sent to schools)
Tip: The Primary ISEE is shorter and less formal, but still benefits from practice and familiarity.
- Raw scores are converted to scaled scores (760–940), then to stanines (1–9)
- Percentile ranks compare your score to others in your grade
- Most schools look at stanines and percentiles for each section
Stanine 5 = average; 7–9 = competitive for selective schools.
SCORE GUIDE
What is a Good ISEE Score?
ISEE scores are reported as stanines (1–9). Here’s how to interpret them and what top schools typically expect.
| Stanine | Description | Percentile Range |
|---|---|---|
| 9 | Highest performance — very top tier | 96th–99th |
| 8 | Highly competitive, top 10–20% | 89th–95th |
| 7 | Above average — competitive for many schools | 77th–88th |
| 6 | Above average, competitive for many schools | 60th–76th |
| 5 | National average | 40th–59th |
| 4 | Slightly below average | 24th–39th |
| 3 | Below average | 11th–23rd |
| 2 | Well below average | 4th–10th |
| 1 | Lowest range | 1st–3rd |
How schools use scores: Each school sets its own score expectations. Many competitive schools look for stanines of 7 or higher in most sections. Some schools focus on the overall profile, not just scores. A “good” score is one that meets your target school’s standards and reflects your best effort.

CHOOSE THE RIGHT TEST
ISEE vs. SSAT: Which Should Your Child Take?
Most private schools accept either test, but each has different strengths. Here’s a side-by-side comparison.
| Feature | ISEE | SSAT |
|---|---|---|
| Administered by | ERB (Educational Records Bureau) | EMA (Enrollment Management Association) |
| Levels | Primary, Lower, Middle, Upper | Elementary, Middle, Upper |
| Test sections | 5 sections (Verbal, Quant, Reading, Math, Essay) | 4 sections (Verbal, Quant, Reading, Writing) |
| Total time | 2.5–3 hours | 2–3 hours |
| Wrong-answer penalty | No — guess freely | Yes — 1/4 point off for wrong answers |
| Vocabulary | Synonyms & sentence completion | Synonyms & analogies (more difficult) |
| Math style | Heavier on quantitative reasoning | Heavier on traditional math content |
| Test attempts per season | 3 attempts per scoring season | Unlimited (Standard test only once per Aug–Jan window) |
| Scoring | Stanines 1–9 + percentiles | Scaled scores + percentiles |
| Best for students who… | Are strong in logic & reading; want freedom to guess | Have a deep vocabulary & strong math foundation |
Our recommendation: Most Texas private schools accept both. Take a diagnostic of each test, then choose the one your child scores higher on. We offer free diagnostic assessments for both — call (877) 638-0707 to set one up.
SCORE IMPROVEMENT
How to Raise Your ISEE Score
Targeted strategies that help students improve across every section of the ISEE.
How long should we prep?
Most families start 3–4 months before test day. Students aiming for top stanines (8–9) often start 5–6 months out, with 1–2 sessions per week plus a full-length practice test every 2–3 weeks.
Want a personalized prep plan?
Our ISEE specialists build a roadmap around your student’s target schools, current level, and test date. We’ll review the diagnostic together and recommend the right number of hours.
Simulate real test conditions with full-length, timed ISEE practice exams. This builds endurance, reveals strengths and weaknesses, and helps with pacing and anxiety.
How to do it:
- Schedule a full-length practice test every 2–3 weeks.
- Use official ISEE materials or reputable online resources.
- After each test, review every incorrect answer and note patterns in mistakes.
- Mimic the real test environment: quiet room, no phone, and only allowed breaks.
Set time targets for each section. Use a timer during practice. Don’t get stuck—move on and return to tough questions later.
Extra detail:
- Break each section into smaller time blocks (e.g., 5 questions per 6 minutes).
- Practice skipping and returning to difficult questions.
- Use the two-pass approach: answer all easy questions first, then tackle the harder ones.
Analyze practice test results to identify weak spots. Focus study time on those sections or question types.
How to do it:
- Keep a log of missed questions by topic.
- Spend extra study sessions reviewing those topics.
- Use targeted practice sets or flashcards for trouble areas.
For Verbal, study word roots, prefixes, and suffixes. For Math, review grade-level concepts, especially fractions, decimals, ratios, and word problems.
Extra detail:
- Make flashcards for unfamiliar words and review daily.
- Practice math facts and mental math to increase speed.
- Read challenging texts to encounter new vocabulary in context.
Write practice essays under timed conditions. Focus on clear structure (intro, body, conclusion) and neat handwriting if testing on paper.
How to do it:
- Use sample prompts and write essays in 30 minutes.
- Ask a teacher or tutor to review your writing for clarity and grammar.
- Outline your thoughts before writing for better organization.
Practice relaxation techniques (deep breathing, positive self-talk). Take practice tests in realistic settings. Build confidence through preparation.
Extra detail:
- Try mindfulness or short meditation before study sessions.
- Visualize success on test day.
- Remember: it’s normal to miss some questions; focus on doing your best.

SAMPLE QUESTIONS
See What ISEE Questions Look Like
One representative question from each section — written in the official ISEE format. These are generic-style examples for familiarization, not retired exam content.
Verbal Reasoning — Synonym
Select the word that most nearly means the word in capital letters.
METICULOUS
- (A) careless
- (B) creative
- (C) thorough
- (D) hesitant
Answer: C. “Meticulous” means showing great attention to detail — very careful and precise. The closest synonym is “thorough.”
Quantitative Reasoning
If 3 pencils cost the same as 2 pens, and 1 pen costs $0.90, how much do 6 pencils cost?
- (A) $1.80
- (B) $2.40
- (C) $2.70
- (D) $3.60
Answer: D. 2 pens cost $1.80, so 3 pencils = $1.80, meaning 1 pencil = $0.60. Therefore 6 pencils cost 6 × $0.60 = $3.60.
Reading Comprehension
“Although the desert appears lifeless during the day, it transforms at night. Many animals — from kangaroo rats to barn owls — emerge after sunset to hunt and forage in the cool air.”
The passage suggests that desert animals are most active at night because:
- (A) there is more food available
- (B) cooler temperatures make it easier to move and hunt
- (C) predators sleep during the night
- (D) the desert is darker at night
Answer: B. The passage explicitly says animals emerge “in the cool air” — an inference about temperature, not food, predators, or visibility.
Mathematics Achievement
A rectangle has a length of 12 cm and a width of 5 cm. What is the length of its diagonal?
- (A) 7 cm
- (B) 11 cm
- (C) 13 cm
- (D) 17 cm
Answer: C. Using the Pythagorean theorem: √(12² + 5²) = √(144 + 25) = √169 = 13 cm.
Essay Prompt
“Describe a time you had to step outside your comfort zone. What did you learn about yourself, and how has that experience shaped the way you handle new challenges today?”
What graders look for: a clear introduction with a specific personal example, organized middle paragraphs with vivid detail, and a thoughtful conclusion. The essay is unscored but sent to schools — clarity, organization, and authenticity matter more than length.

FAQS
Frequently Asked Questions
Quick answers to the questions parents ask us most often about the ISEE.
Registration is handled by the ERB (Educational Records Bureau) at iseetest.org. You’ll create a parent account, choose between online or paper format, and pick a test date and location. Most students take the ISEE between September and January for fall admission.
The standard ISEE registration fee is approximately $125–$200 depending on test format and location. Late registration adds a fee. Fee waivers are available for qualifying families — check the ERB site for current pricing and waiver details.
The content is identical. The online ISEE is offered at Prometric centers and at home with remote proctoring. The paper ISEE is offered at large group sites and some independent schools. Most students choose online for the flexibility — just make sure your student practices on screen if testing online.
Yes — the ERB allows students to take the ISEE up to three times per admission season, with each attempt in a different testing window (Aug–Nov, Dec–Mar, Apr–Jul). All scores are reported to schools, so most families plan one strong sitting rather than multiple attempts.
Online ISEE: scores typically arrive in your ERB account within 2–3 business days. Paper ISEE: scores take 7–10 business days. The essay is not scored but is sent unedited to every school you designate.
Stanines run from 1 to 9, with 5 as average. Most competitive private schools target stanines of 7–9 across all four sections. Top-tier schools (Hockaday, St. John’s, St. Stephen’s, etc.) typically see admitted students at 8–9. See our school benchmarks above for region-specific ranges.
Yes. Students with documented learning differences (504 plan, IEP, or psycho-educational evaluation) can request accommodations such as extended time, separate room, or breaks. Apply early — ERB approval typically takes 4–6 weeks. Submit your documentation through the parent account when you register.
Most families prep for 3–4 months with 1–2 sessions per week. Students starting from a lower baseline or aiming for highly competitive schools may need 5–6 months. The most important factor is consistency and at least 3–4 full-length practice tests during the prep window.
Most schools accept either. Pick based on which schools your student is applying to — some schools strongly prefer one. The ISEE has no wrong-answer penalty, while the SSAT does. Students who guess strategically often do better on the ISEE. See our comparison table above for the full breakdown.
For students applying for the following school year, we recommend testing in October or November. This gives time for one retake if needed before most application deadlines (typically January 15). Check each target school’s deadline — some require ISEE scores by early December.
