Most ISEE essay tips you find online stop at "respond to the prompt and write neatly" — and if your son is applying to Strake Jesuit College Preparatory in Houston, that advice leaves out the part that actually matters. The ISEE Upper Level essay section carries no numerical score from ERB, yet every word your son writes goes straight to Strake Jesuit admissions. I've seen students lose ground on otherwise competitive files because their essay felt rushed, generic, or completely disconnected from the thoughtful young man described in their recommendations. Here's what Strake Jesuit admissions readers are actually looking for — and how 30 minutes of timed writing can become one of the strongest parts of his application.

Is the ISEE Essay Scored — And How Much Does It Matter for Strake Jesuit ISEE Admissions?
ERB does not assign a numerical score to the ISEE essay. There is no 1–6 rubric, no stanine, no percentile rank. That fact leads a lot of families to treat the 30-minute writing sample as an afterthought — and at Strake Jesuit, that is a real mistake.
Every ISEE essay is photocopied and sent to each school your son designates, including Strake Jesuit. Admissions readers review it alongside his transcripts, teacher recommendations, and application essays. They want to see that the student who earned those grades is the same student who shows up on paper. A disorganized or superficial writing sample creates doubt. A clear, honest, purposefully structured one reinforces every other strength in the file.
Strake Jesuit is a Jesuit institution — and that matters more than most families realize. Jesuit education prizes intellectual competence, self-awareness, and a willingness to engage honestly with difficult questions. When admissions readers open an uncoached, timed writing sample, they are specifically looking for those qualities. Your son cannot revise it after the fact. He cannot run it past a tutor. What he writes in that room is what they see.
How to Write an ISEE Essay That Aligns With Strake Jesuit's Jesuit Values
The ISEE Upper Level essay prompt is personal and reflective. Your son will see two topic choices and pick one — both will ask him to write about himself: a goal, a challenge, a person who influenced him, or a moment that changed his thinking. There are no wrong topics. There are, however, weak approaches.
Jesuit admissions readers are not impressed by polished-sounding language that says nothing. I've watched students lose that unscored section by leaning on generic phrases — "always wanting to be the best I can be" — instead of saying something real. A student who writes three detailed paragraphs about failing a math test and what he learned from it will outperform a student who writes five vague paragraphs about striving for excellence.
Here is a concrete structure that works within 30 minutes and connects with Jesuit values. If your son practices it ahead of time with the Essay Writing Practice Tests at stemcriticalthinking.com, he will walk in knowing exactly what to do when the clock starts:
- Minutes 1–4 — Outline: One specific experience or idea. Two or three concrete supporting details. One honest reflection on what it revealed about him.
- Minutes 4–26 — Draft: Open with the specific moment, not a broad statement. Develop each detail in its own paragraph. Close with what it means for who he is becoming.
- Minutes 26–30 — Review: Fix sentence fragments, check verb tense consistency, confirm the opening directly answers the prompt.
The phrase "who he is becoming" matters specifically in a Jesuit context. Strake Jesuit is not looking for a finished product. They are looking for a young man who is open to growth — one of the core characteristics Jesuit schools evaluate in every applicant.
What ISEE Stanine Score Does My Son Need for Strake Jesuit Upper Level Admissions?
Strake Jesuit does not publish a minimum stanine cutoff. Based on community-observed data from ERB score reporting forums and Houston-area admissions consultants, a stanine of 6 to 7 is the competitive range for most admitted students. A stanine of 6 places your son in roughly the 60th to 77th percentile nationally. A stanine of 7 reaches the 78th to 89th percentile.
Each of the four multiple-choice sections is scored on a scale of 760–940. Those raw scaled scores convert to stanines. There is no penalty for wrong answers — your son earns credit only for correct responses, so he should never leave a question blank.
The Quantitative Reasoning section is where I've seen students lose the most ground. It tests word problems and quantitative comparisons without a calculator, and it rewards multi-step logical reasoning — not formula recall. That is an honest distinction: you cannot cram your way to a better stanine on this section. It takes weeks of consistent practice. Our STEM Critical Thinking practice tests are built around exactly that kind of problem.
A strong transcript can support a stanine 6 application. A stanine 5 or below in Verbal or Math will draw scrutiny at a school with Strake Jesuit's academic rigor, even with excellent recommendations.
ISEE Test Dates, Deadlines, and Document Requirements for Strake Jesuit Applicants
The online application deadline for incoming freshmen is January 15. All supplemental documents — ISEE scores, middle school transcripts, and three recommendation letters — are due January 31. That two-week gap after the application deadline exists for a reason, but January 31 is not a soft date. Nearly all available seats are filled by the end of February.
Strake Jesuit offers on-campus ISEE testing in November and January. Registration deadlines for those dates update each year — confirm current dates directly with Strake Jesuit's admissions office, since the windows shift slightly from one cycle to the next. If your son misses both on-campus dates, any ERB-approved external site, including at-home proctored testing, is accepted. Use school code 570964 to send scores directly to Strake Jesuit.
Decision letters and financial aid notifications arrive together in mid-March, typically around March 6. Both come in the same mailing so you can evaluate the full offer at once.
How the ISEE Upper Level Differs From the SAT and ACT — and What That Means for How to Write the ISEE Essay
The ISEE Upper Level is an aptitude-plus-achievement exam designed for students entering grades 9 and 10. The SAT and ACT measure what high schoolers have already learned. The ISEE also measures reasoning potential — how well your son can think through a problem he has never seen before.
The Quantitative Reasoning section does not just test algebra formulas. It asks your son to set up and solve a multi-step comparison problem under time pressure, without a calculator, often with unfamiliar phrasing. That is a reasoning skill. It takes weeks of real practice to improve, not a weekend of reviewing notes.
The Verbal Reasoning section tests synonyms and sentence completion. A student with a wide reading vocabulary has a genuine advantage here. If your son's independent reading is limited, start building vocabulary now — 10 new words per day, used in sentences, reviewed weekly. Small habits compounded over 12 weeks make a measurable difference.
The students I've seen improve their stanine scores the most are the ones who practice full-length timed sections — not just content review. Simulate real test conditions: no calculator, pencil only, timed to the minute. For the essay specifically, that means practicing on personal-reflective prompts in exactly 30 minutes with no outside help. That is the only kind of preparation that actually transfers to the testing room.
ISEE Testing Accommodations and At-Home Options for Strake Jesuit Essay Prep
If your son has a documented learning difference — such as ADHD, dyslexia, or a processing disorder — extended-time testing accommodations are available for the ISEE. At Strake Jesuit's on-campus test dates, standard testing ends at 12:30 PM. Extended-time testers are picked up at 1:30 PM. Accommodations must be approved through ERB in advance. Start that process at least six to eight weeks before your target test date — the paperwork takes longer than most families expect.
At-home proctored ISEE testing is accepted by Strake Jesuit. This option works well for families who cannot make either on-campus date or who want a familiar environment for test day. The same scoring standards apply, the essay section is included, and the copy still goes to Strake Jesuit admissions. There is no disadvantage to testing off-campus as long as you enter school code 570964.
Large-print formats are also available through ERB. Visit erblearn.org to confirm current accommodation request procedures — documentation requirements and timelines are updated periodically.
Frequently Asked Questions: ISEE Essay Tips and Strake Jesuit Upper Level Admissions
Q: Is the ISEE essay scored?
A: No. ERB does not assign a numerical score to the ISEE essay. A copy is forwarded to every school your son applies to, including Strake Jesuit. Admissions readers use it to assess writing maturity, voice, and whether his written expression matches the rest of his application. A weak essay can raise doubts; a strong one can tip a borderline file.
Q: What should my son write about in the ISEE essay?
A: He should respond directly to the prompt without over-engineering the topic. The ISEE Upper Level gives two topic choices — he picks one. Jesuit admissions readers value intellectual honesty and self-awareness over impressive vocabulary. Encourage him to pick one specific experience or idea, develop it with concrete detail, and close with a reflection on what it revealed about who he is. Timed essay practice under realistic conditions — like the Essay Writing Practice Tests at stemcriticalthinking.com — builds exactly that instinct.
Q: How long is the ISEE essay section?
A: The essay section is 30 minutes long. A target response is 300 to 400 words. Spend the first 3 to 4 minutes outlining — one clear thesis, two or three supporting details, and a closing reflection. That leaves roughly 22 minutes to write and 4 minutes to review. Skipping the outline almost always produces a scattered response that admissions readers notice immediately.
Q: What ISEE stanine score does my son need to be competitive at Strake Jesuit?
A: Strake Jesuit is widely cited in the ERB community as a stanine 6 to 7 school. A stanine of 6 places a student in roughly the 60th to 77th percentile nationally; stanine 7 reaches the 78th to 89th percentile. These are community-observed estimates — Strake Jesuit does not publish an official cutoff. Strong transcripts and recommendations can support a stanine 6 file, but a stanine 5 or below in math or verbal will draw scrutiny given the school's rigorous curriculum.
Q: Does my son have to take the ISEE at Strake Jesuit's campus?
A: No. Strake Jesuit accepts ISEE scores from any ERB-approved testing site, including at-home proctored testing. If your son tests off-campus, use Strake Jesuit's school code — 570964 — so his scores are sent directly. On-campus test dates at Strake Jesuit are offered in November and January, which align with the January 15 application and January 31 document deadlines.
Q: How many times can my son take the ISEE, and will Strake Jesuit see all his scores?
A: Students may take the ISEE once per testing season — Fall (August through November), Winter (December through March), and Spring/Summer (April through July) — for a maximum of three attempts in 12 months. Strake Jesuit will accept and review multiple scores. There is no official score-choice policy, so all scores sent to the school are visible to admissions readers. A clear upward trend across attempts generally reads positively.
Q: When is the Strake Jesuit application deadline, and what documents are due?
A: The online application deadline for incoming freshmen is January 15. Supplemental documents — including ISEE scores, middle school transcripts, and three recommendation letters from the Math teacher, English teacher, and Principal or Counselor — are due January 31. Applications submitted after January 15 are reviewed on a rolling basis, but nearly all seats are filled by end of February. Submitting in November or December is the safer move.
Q: When will we receive an admissions decision from Strake Jesuit?
A: Decision letters and financial aid notifications are sent together in mid-March, typically around March 6. Both arrive in the same mailing so your family can evaluate the full offer at once. The enrollment deposit deadline is included in that letter — respond promptly, because seats are not held indefinitely once decisions go out.
