A clear plan turns thirty minutes into a confident, organized essay that impresses admissions readers.
People have been organizing their ideas before writing for thousands of years. Ancient Greek speakers used a method called rhetoric (the art of persuasive speaking and writing). They would plan every argument before stepping in front of an audience. That same idea — plan first, write second — is still the secret weapon of great writers today.
Here's the big question the ISEE essay asks you to answer: How can you write a clear, personal, and well-organized essay when you only have 30 minutes? The answer is planning. Spending just 3–5 minutes brainstorming and outlining saves you time, reduces stress, and helps you write a stronger essay.
Essay planning has two main stages. First, you brainstorm (write down every idea that comes to mind). Then, you outline (pick the best ideas and put them in order). Think of brainstorming as dumping puzzle pieces onto a table, and outlining as putting those pieces together.
The diagram below shows how brainstorming and outlining work together. Notice how brainstorming is messy and creative, while the outline is neat and organized. Both stages are important — you need the messy stage to discover great ideas, and the organized stage to present them clearly.
Look at the left side of the diagram. There are eight ideas scattered around. Not all of them are strong choices. The writer circled the three ideas with the most specific detail and moved them to the outline on the right. Each idea became a body paragraph with a topic and a supporting detail.
There are several brainstorming techniques you can use on the ISEE. The key is to pick one method that works for you and practice it until it becomes automatic. Here are the three most popular methods.
Read the prompt and then write down every idea that pops into your head. Don't stop to think about whether each idea is good or bad. Just write for about 90 seconds. You should aim for 5–8 ideas. Then go back and circle your 2–3 favorites.
Write the main topic in the center of your scratch paper. Draw lines out from the center, like a spider web, and write related ideas at the end of each line. This method is great if you think visually. It helps you see how ideas connect to each other.
Ask yourself: Who? What? When? Where? Why? Answer each question about your topic. This method works well if you're writing about a personal experience because it helps you recall specific details.
Once you have your best ideas from brainstorming, it's time to build your outline. An outline is a simple map of your essay. It tells you what each paragraph will be about. For the ISEE, your outline should have four to five parts: an introduction, two or three body paragraphs, and a conclusion.
| Paragraph | Purpose | What to Write in Your Outline |
|---|---|---|
| Introduction | Hook the reader and state your main idea (thesis) | A few words about your hook + your thesis sentence |
| Body 1 | First supporting example or story | Topic + 1–2 specific details |
| Body 2 | Second supporting example or story | Topic + 1–2 specific details |
| Body 3 (optional) | Third example if time allows | Topic + 1 detail |
| Conclusion | Restate your thesis and leave a lasting impression | Reworded thesis + a forward-looking thought |
Your outline does not need to be pretty. It can be messy handwriting, abbreviations, or even little drawings. The only person who sees it is you. Its job is to keep you focused so you don't get stuck while writing.
Let's walk through the entire planning process using a real ISEE-style prompt. Follow each step carefully.
Notice how the outline uses short phrases, not full sentences. That's the point — you're creating a roadmap, not a rough draft. When you start writing, you'll expand each line of the outline into a full paragraph. This saves you from staring at a blank page and wondering what to write next.
Not all plans are created equal. Let's compare what a strong outline looks like versus a weak one. Understanding the difference will help you create better plans on test day.
| Feature | Weak Plan ✗ | Strong Plan ✓ |
|---|---|---|
| Thesis | "I like trying new things." | "Joining debate taught me that being scared is the first step to growing." |
| Details | Vague: "It was fun" or "I learned a lot" | Specific: "Froze at the podium, Maya helped me at lunch, won 2nd place" |
| Structure | No outline — just starts writing randomly | Clear intro → body 1 → body 2 → body 3 → conclusion |
| Transitions | Jumps from idea to idea with no connection | Uses "After that," "However," "Eventually" to connect paragraphs |
| Time Use | Spends 0 minutes planning, then runs out of ideas midway | Spends 3–5 minutes planning, writes smoothly for 20 minutes |
On the real ISEE, you get exactly 30 minutes for your essay. That sounds short, but with good planning, it's plenty of time. Here's how to divide those minutes wisely.
| Phase | Minutes | What You're Doing |
|---|---|---|
| Plan | 3–5 | Read prompt, brainstorm ideas, build a quick outline |
| Write | 18–21 | Write your intro, body paragraphs, and conclusion following your outline |
| Revise | 3–5 | Re-read your essay. Fix spelling, add a missing word, improve a sentence |
Now it's your turn! Work through these five activities. They start easy and get more challenging. Each one builds a different planning skill that you'll use on the actual ISEE.
Planning your ISEE essay takes just 3–5 minutes and makes the rest of your writing time much easier. Start by reading the prompt carefully and underlining the key words. Then brainstorm using a Quick List, Web, or the 5 W's method. Choose your 2–3 strongest ideas — the ones with the most specific, personal details — and build them into a simple outline with an introduction, body paragraphs, and a conclusion.
Remember the key principles: always show, don't tell by using concrete anecdotes rather than vague statements. Include a vivid hook in your introduction, a clear thesis statement, and plan transitions between paragraphs. Save 3–5 minutes at the end to revise for spelling, clarity, and flow. A strong plan is your secret weapon for writing a confident, organized essay that impresses admissions readers.
