Simple English SOP: A Guide for Non-Native Writers

Simple English SOP: A Guide for Non-Native Writers

Simple English is what Stanford and Berkeley ask for. Stanford's prompt says "Describe succinctly" your reasons, preparation and plans. Berkeley's guidance says "Write technically, or in the style of your discipline. Faculty are the people who read these statements." Neither asks for literary style, rare words or idioms.

Our view: the English problem to fix first in a non-native applicant's statement is not grammar. It is abstraction: "passion", "deeply fascinated", "broaden my horizons". These phrases say nothing a faculty reader can check. A plain sentence with an exact technical noun says more. This page gives seven rules, each with a before-and-after edit, and a list of phrases to cut. If you have a draft, a statement of purpose review reads it for content and fit.

The Stanford, Berkeley and Harvard Kennedy School pages quoted below were checked on October 30, 2026.

What the prompt asks you to prove

Read the two prompts as instructions about content, not style.

"Describe succinctly your reasons for applying to the proposed program at Stanford, your preparation for this field of study, research interests, future career plans, and other aspects of your background and interests which may aid the admission committee in evaluating your aptitude and motivation for graduate study. The maximum recommended length is 1,000 words."

That is Stanford's general prompt. It notes that "The exact prompt you see on the application (including recommended length) may differ depending on the graduate program you select."

"Please describe your aptitude and motivation for graduate study in your area of specialization, including your preparation for this field of study, your academic plans or research interests, and your future career goals."

That is Berkeley's prompt. Berkeley's writing tips add: "write in an active, not a passive voice", "Demonstrate everything by example", and "Approximately 500 to 1,000 well-selected words is better than more words with less clarity and poor organization."

Harvard Kennedy School's senior director of admissions and financial aid wrote, in its September 10, 2026 AI guidance: "I would so much rather read an application that isn't 100% polished versus one that is technically perfect but devoid of passion and authenticity."

So the published requirement is content: preparation, interests, plans, fit. Our recommendation is the style that delivers content fastest. The countercase: in some humanities fields the "style of your discipline" is more discursive, and a reader may expect longer sentences that build an argument. Plain still beats decorative there, but very short sentences can read as thin. Read published writing in your field and match its register.

Seven rules for simple, exact English

Every before-and-after pair below is a constructed example, written by us, not a real applicant statement.

Rule 1: Subject, verb, object

Before: The completion of a project on traffic prediction was achieved by me in my final year.

After: In my final year, I built a traffic prediction model.

Berkeley asks for active voice. Put the person doing the work first.

Rule 2: One idea per sentence

Before: I worked on soil samples and I also learned R and this experience made me interested in environmental data, which I want to study further at your university.

After: I analyzed 80 soil samples in R. That project made me want to study environmental data science.

Rule 3: Numbers and names instead of adjectives

Before: I gained extensive experience in a very reputed laboratory.

After: I spent 14 months in a polymer chemistry lab, running gel permeation chromatography twice a week.

The second sentence is longer and better, because every word can be checked.

Rule 4: Use your field's terms exactly

Before: I studied how to make the computer understand pictures better.

After: I trained convolutional neural networks for image segmentation.

Berkeley's line is the reason: faculty read these statements. Use the term they use.

Rule 5: No idioms

Before: Machine learning has always been my cup of tea, and I want to take it to the next level.

After: I want to specialize in machine learning for medical imaging.

An idiom used slightly wrong is more noticeable than no idiom.

Rule 6: Past tense for done work, future for plans

Before: In my thesis I am developing a sensor and I will test it last semester.

After: In my thesis I developed a humidity sensor and tested it over one semester. In your program I want to work on low-power sensor design.

Rule 7: Cut intensifiers

Before: I am extremely passionate and highly motivated to pursue this very prestigious program.

After: I am applying to this program for its coursework in transportation planning.

Intensifiers add length, not meaning. Stanford asks for "succinctly".

Words to cut

Every phrase below is a constructed example we wrote. Delete it, or replace it with the fact it was hiding.

Is my English good enough?

Your English level is measured separately. Stanford sets minimum TOEFL and IELTS scores and requires an English Placement Test for incoming students whose scores fall below its exemption line (Stanford test scores). The test shows proficiency. The SOP shows your preparation and plans.

Our view: if your English is correct and plain, it is good enough for the statement. Spend the time you would spend on vocabulary on specifics instead. If you are not sure the meaning comes through, ask one person in your field, ideally someone who reads English papers, to read it and tell you what they think your research interest is. If they cannot say it in one sentence, the problem is content, not English.

The American SOP and cultural differences guide covers the other half of this problem: how directly to describe your own work.

Grammar tools without losing your voice

Accept corrections. Reject rewrites. A tool that changes "make" to "made" is fixing grammar. A tool that turns your sentence into "My research endeavors have equipped me with profound insights" has replaced your content with the abstraction this page tells you to cut.

The rules matter here too. Harvard Kennedy School permits AI "for assisting with edits to your materials and/or identifying issues such as spelling or grammatical errors", and its certification says your materials "have not been written, rewritten, or translated by anyone other than yourself." Other programs word this differently; the grammar-checker policy page and the do grad schools check for AI guide cover what schools say.

You may also have read that plain English gets flagged. A 2023 study, Liang et al., found AI detectors "consistently misclassify non-native English writing samples as AI-generated." Do not answer that by letting a tool rewrite your sentences: under a certification like HKS's, your materials must not be "rewritten … by anyone other than yourself". The translated SOP guide covers what the study did and did not test, and the case where you drafted in another language first.

Constructed example: one paragraph rewritten

Constructed example, written by us, not a real applicant statement. Context (invented): an applicant to an MS in civil engineering.

Before: Since my childhood I have been deeply fascinated by the marvels of civil engineering. During my undergraduate studies at a reputed institution, I gained extensive exposure to various projects which broadened my horizons. I am now highly motivated to pursue an MS at your esteemed university, which has world-class faculty and state-of-the-art facilities.

After: In my final-year project I designed a stormwater drainage plan for a 2-kilometer road section and modeled it in SWMM. The model showed that the existing drains overflow in a 10-year storm. I want to study urban hydrology so I can design drainage for cities that are growing faster than their infrastructure. Your program's course in green infrastructure design matches this goal.

The "before" paragraph is 53 words and contains no fact a reader can check. The "after" paragraph is 62 words and contains a project, a tool, a result, a goal and a reason for the program. Its English is simpler. The project details are invented for the example. The SOP mistakes guide covers the clichés in the "before" version from another angle.

Questions about simple English in an SOP

Is it bad to use simple English in a statement of purpose?

No. Stanford asks you to write "succinctly" and Berkeley asks you to write "technically". Simple and exact is what both prompts reward.

Should I use advanced vocabulary to impress the committee?

No. Use your field's technical terms exactly. Avoid general "impressive" words that add no fact.

Do grammar mistakes hurt my SOP?

Neither Stanford nor Berkeley says how grammar is weighed. Fix the errors you can find, because they distract from your content, but do not let a tool rewrite your sentences.

How long should a simple English SOP be?

Stanford's general prompt gives a "maximum recommended length" of 1,000 words. Berkeley suggests "Approximately 500 to 1,000 well-selected words". Check your program's own limit. Your test score and your statement are judged separately; for the test choice, see Duolingo English Test acceptance at US grad schools.

Phrases like 'world-class education' usually sit in a why USA paragraph that the prompt never asked for.
