How to prepare for the ISEE: a calm, eight-week plan

Start six to eight weeks before the test. Take one timed mock to see which question types are new and where the clock bites, then do short daily drills on the weakest section, build vocabulary every day, practise two or three timed essays, and take a second mock to check progress. Keep sessions short and the tone encouraging: the aim is a child who walks in having already done this once, not one who has been drilled into worry.

How long does it take to prepare for the ISEE?

Six to eight weeks of short, regular practice suits most children. Start earlier if a first mock shows many unfamiliar math topics, and plan backward from the testing season and your earliest school deadline.

Two things improve quickly with practice: pace, and comfort with the question formats. Both usually show real change within three or four weeks. Two things improve slowly: vocabulary and math topics not yet taught at school. Those reward an earlier start and a little every day.

ERB allows one test per testing season (Fall, Winter and Spring/Summer), so a disappointing first sitting usually means waiting for the next season. That makes the first sitting worth preparing for properly. The seasons, fees and levels are in the ISEE test guide.

What should an ISEE study plan look like week by week?

Map, then fix, then rehearse: a full mock in week 1, daily drills on the weakest areas in weeks 2 to 6 with vocabulary throughout, a second mock and essays in week 7, and a light, calm final week.

An eight-week ISEE plan (our recommendation, about 15 to 25 minutes a day)
Week	Focus	What to do
1	Map	Take the free full mock, sections in order with breaks. Note each section's percent correct and any blanks.
2	Weakest section	One 12-question drill a day on it. Read every explanation together. Start ten words a day.
3	Weakest section	Keep drilling. Add quantitative comparison practice if that format was new.
4	Second weakest	Switch the daily drill. Write the first timed essay at the weekend.
5	Math by hand	Fractions, percents and equations without a calculator, ten minutes a day, plus a drill.
6	Mixed drills	Rotate all four sections. Read ERB's "What to Expect" guide for your child's level.
7	Rehearse	Second full mock on new questions, then a second timed essay. Compare bands with week 1.
8	Rest and review	Light review of the words and rules collected. Normal sleep. No new material.

If you have only three or four weeks, keep weeks 1, 2, 4 and 7 and drop the rest. If you have longer, add vocabulary and reading time rather than more mocks: two or three full mocks are enough for most children.

What does each ISEE section reward, and how do you practise it?

Verbal Reasoning rewards ready vocabulary; Quantitative Reasoning rewards testing cases and reasoning before calculating; Reading rewards proving answers from the text; Mathematics Achievement rewards careful written working.

Verbal Reasoning
30 seconds a question
Ten new words a day, each used in a sentence at dinner. Learn common roots (bene, mal, chron, spect, port). For sentence completions, find the clue word and predict before looking.
Quantitative Reasoning
about a minute a question
Learn the four fixed comparison choices. When a letter appears, test a positive number, zero, a negative and a fraction. Estimate before calculating.
Reading Comprehension
about a minute a question
Read widely: science, history and opinion pieces, not only stories. Summarize each paragraph in a few words, then point to the line that proves each answer.
Mathematics Achievement
about 50 seconds a question
Work by hand every time. Rework each miss until it comes out right without help, then do two more of the same kind.

ISEE-style question 1 · Quantitative comparison
Column A: 30% of 50 Column B: 50% of 30 Compare the quantity in Column A with the quantity in Column B.
1. AThe quantity in Column A is greater.
2. BThe quantity in Column B is greater.
3. CThe two quantities are equal.
4. DThe relationship cannot be determined from the information given.
Worked answer
C: The two quantities are equal.. 30% of 50 is 0.3 × 50 = 15, and 50% of 30 is 0.5 × 30 = 15. They are equal. (a% of b always equals b% of a.)
1. Column A: 0.3 × 50 = 15.
2. Column B: 0.5 × 30 = 15.
3. Both are 15, so the quantities are equal.
The trap: Assuming the column with the bigger number (50%) must be bigger. Work both out: it takes ten seconds.
ISEE-style question 2 · Supporting detail
According to the passage, logs like this one are valuable to historians mainly because
1. Athey were kept the same way, in the same place, for many years
2. Bthey describe exciting rescues at sea
3. Cthe keepers wrote them for scientists
4. Deach entry is long and detailed
Worked answer
A: they were kept the same way, in the same place, for many years. The second paragraph gives the reason: "Because the entries were made in the same place, in the same way, for so many years," they form a long, unbroken record.
1. Find the word "because" in paragraph 2.
2. It gives the reason: same place, same way, many years.
3. The third choice is contradicted in paragraph 3, and the fourth in paragraph 1.
The trap: Choosing an answer the passage contradicts. Each wrong choice here is ruled out by a specific line.

How should my child practise the ISEE essay?

Write two or three essays in 30 minutes each on prompts like the ones below, then read each one back together against the checklist. ERB does not score the essay, but every school on your list receives a copy.

Practice prompts in the style of the ISEE (written for LifeScore, not ERB prompts):

Describe a time you changed your mind about something that mattered to you. What made you change it?
If you could add one class to your school's timetable, what would it be, and why would it be worth the time?
Write about someone who has taught you something important outside a classroom.
Some people say mistakes are the best teachers. Do you agree? Use an example from your own life.
Describe a place that matters to you and explain why it matters.
What is one thing you would change about your town or neighborhood, and how would you start?

The checklist to read back against:

Answer the exact prompt in the first two or three sentences, so the reader knows where the essay is going.
Spend three to five minutes planning: one main point and two specific examples or moments.
Write in paragraphs: an opening, two body paragraphs (one for each example) and a short closing.
Use real details (a name, a place, what was said) instead of general statements like "it was a great experience."
Write in your own voice. Schools read the essay to get to know the applicant, not to count long words.
Keep the last three minutes to reread and fix missing words, spelling and sentences that run on.

Resist the urge to rewrite the essay for your child. Schools are looking for a real twelve-year-old's writing, and the most useful feedback is one thing that worked and one thing to try next time.

What is the most useful thing a parent can do?

Set up the routine and protect the mood. A child who practises little and often, with someone interested in how they think, improves more than one pushed through long sessions or told what a score means about them.

Keep sessions short (10 to 25 minutes) and at a regular time, so practice is a habit rather than an event.
Ask about the thinking ("how did you decide?") more than the result. Praise effort and good routines.
Explain early that the ISEE compares applicants with a strong group, so a middle stanine is normal and schools read reports that way.
Watch for signs of worry, and dial practice down if they appear. A rested child does better than a drilled one.
Keep the test in proportion: schools look at grades, recommendations, the interview and the essay too.

Does my child need an ISEE tutor?

Not always. Many children prepare well with timed practice and a parent's support. A tutor helps most with a stubborn topic or a child who works better with someone outside the family. ISEE tutors on Wyzant list about $40 to $500 an hour, most between $80 to $200.

Whatever you choose, the timed practice has to happen: no tutor can make 40 vocabulary questions in 20 minutes feel normal except by your child doing it. If you use a tutor, bring them the section breakdown from a full mock, so the paid hours go on the topics that need explaining rather than on practice your child can do alone.

The free ISEE practice test gives that breakdown, and the drills on the Middle Level page give the daily practice.

How do we get ready for ISEE test day?

Confirm the time, place or computer setup, and what to bring, a few days ahead; sleep normally the week before; eat a good breakfast; and remind your child to answer every question, because wrong answers are not deducted.

A week before: read ERB's instructions for your testing option (at home, in an ERB office, at a Prometric center or at a school) and check any equipment needed.
Two days before: stop new practice. A short review of the word list is plenty.
The night before: normal bedtime. Lay out what is needed, including a snack and water for the breaks if allowed.
The morning: a good breakfast and plenty of time. Keep the conversation light.
Afterwards: ask what your child enjoyed or found interesting, not how they did. The report will come.

When the report arrives, ISEE scores explained shows how to read the scaled scores, percentiles and stanines. More practice questions with full working are on ISEE sample questions.

Frequently asked questions

How many hours should my child study for the ISEE?

Most children do well with 15 to 25 minutes most days for six to eight weeks, plus two full mocks. Long sessions add fatigue faster than skill.

Is the ISEE hard to prepare for?

The formats and the pace are quick to learn with practice. Vocabulary and math topics not yet taught take longer, which is why an early start helps.

Should my child guess on the ISEE?

Yes. Wrong answers are not deducted, so a blank is always worth less than a guess.

Where can I find official ISEE practice?

ERB publishes free "What to Expect on the ISEE" guides for each level, with example questions and test-day information.

Is this the real ISEE?

No. It is an ISEE-style practice test with original questions written for LifeScore. LifeScore is not affiliated with ERB, and ISEE is ERB's registered trademark.

Do we have to pay?
