California Institute of Technology essay review
California Institute of Technology prints eight supplemental prompts for 2026-27 and asks every applicant to write six of them, capped at 150-200 words, 200 words and 100-150 words. A NudgeEssay review reads your draft against the California Institute of Technology prompt you pick, not against a general checklist: six rubric bands scored 1 to 5, notes on your own sentences in the margin, a map of where a reader's attention holds and where it drops, and a ranked list of fixes with the biggest one first. The first fix and the line a reader kept come back free; the full marked-up report is $49 for one essay or $299 for 20.
The California Institute of Technology prompts and deadlines below were read on California Institute of Technology's own admissions site on 2026-08-30. NudgeEssay is not affiliated with California Institute of Technology and makes no claim about any admissions decision.
What California Institute of Technology asks you to write
Word for word, from California Institute of Technology’s own admissions pages. Pick the one your draft answers in the box below and the read is judged against that prompt’s own asks.
Supplement 1 · 150-200 words
Area of interest. Caltech students are not required to declare a major until the end of their first year. If you had to choose an area of interest or two today, what would you choose? Why did you choose your proposed area of interest? If you selected 'other', what topics are you interested in pursuing?
Supplement 2 · 200 words
Scholarly Character, option 1. COLLABORATION: STEM as shared learning. Tell us about a time your learning in STEM was shaped by another person or group, either because you needed help, offered help, changed your thinking through collaboration, or contributed to someone else's understanding. What did that experience teach you about learning and working with others?
Supplement 3 · 200 words
Scholarly Character, option 2. PROCESS: The thought behind the outcome. Tell us about a time your approach to a STEM problem, concept, or project mattered as much as the outcome. How did you work through uncertainty or persist creatively in tackling the problem? What would you still defend about your process, regardless of the outcome?
Supplement 4 · 200 words
Scientific Drive, option 1. LEARNING: STEM as a never-ending rabbit hole. Regardless of your STEM interest listed above, take this opportunity to nerd out and talk to us about whatever STEM rabbit hole you have found yourself falling into. Be as specific or broad as you would like.
Supplement 5 · 200 words
Scientific Drive, option 2. PURSUING: STEM as sustained intellectual engagement. Tell us about a STEM question, problem, idea, or project that has held your attention over time. What drew you to it, how have you pursued it, and what do you still want to understand?
Supplement 6 · 200 words
Scientific Drive, option 3. MAKING: STEM as creation. Tell us about something you created, tested, repaired, modeled, coded, built, or redesigned. What problem were you trying to solve and what did the process reveal to you?
Supplement 7 · 100-150 words
Fun question. Caltech students bring more than academic ability to the communities they join. What is something you would be excited to do, share, teach, make, start, or contribute as part of the Caltech community?
Supplement 8
Optional academic short answer. Caltech cares about context. Is there anything about your academic preparation, coursework, school context, or learning experiences that would help us better understand your readiness for Caltech?

What the review does to your California Institute of Technology essay
It reads the draft cold, the way a stranger with four hundred more files to get through reads it, and answers the question that decides the essay: what is still there a week later. Then it scores six rubric bands from 1 to 5, each with a short quote from your own essay that drove the band and two or three sentences on what would raise it.
It marks your own sentences in the margin, maps where a reader’s attention holds and where it drops across the draft, screens for the patterns that read as AI-written or consultant-written, names the stock archetypes the essay is falling into, and ranks the fixes with the biggest one first. It points at your own material and never writes a sentence for you to paste.
Prompt fit is judged first, before any opinion of the writing: each distinct ask in the California Institute of Technology prompt is checked separately, because an essay aimed near the prompt rather than at it is the most common fatal miss in a paid draft.
All 23 checks are listed on what the review checks. Seven complete reports on sample essays are published unedited, exactly as the engine wrote them, on the samples page, and what a college essay grader leaves out explains where the six bands stop and the read begins.

What California Institute of Technology reports about admissions
California Institute of Technology admits 2.6% of applicants. In the federal admissions survey it reports that SAT and ACT scores are neither required nor recommended.
From the federal College Scorecard, pulled 2026-09-17. Score figures describe enrolled students, not applicants and not admits, and they are not a cutoff. No admission probability is stated anywhere on this site, because colleges do not publish admit rates conditional on a score, so any single percentage would be invented. The free chance me tool sorts a list into reaches, targets and likelies and gives no percentage either.
