When Should My Child Start Studying for the CPS Selective Enrollment Exam? (2025-2026 Guide for Parents)

If your child is considering applying to one of Chicago’s top CPS Selective Enrollment High Schools (SEHS)—like Payton, Jones, Northside, or Whitney Young—you’re probably wondering the same thing thousands of parents Google each year:

“When should my kid start studying for the CPS selective enrollment exam?”

The short answer: Most students should begin preparing 6–12 months before they take the exam.
The long answer: it depends on your child’s baseline, goals, and study habits. Below is a full guide to help you time it right.

The Ideal Timeline at a Glance

• 12 months before the exam: Best for students aiming for top-tier schools or those who need stronger foundations in math/reading.

• 6 months before the exam: Ideal for strong students who just need targeted practice.

• 3 months before the exam: Minimum recommended for most students.

• 1 month or less: Cramming—not recommended, but you can still make progress with focused practice.

Understanding the CPS Selective Enrollment Exam

The SEHS Entrance Exam tests four core areas:

• Reading Comprehension

• Vocabulary

• Math computation

• Math word problems

It’s competitive. Perfect or near-perfect scores are common among accepted students for top-tier high schools. This is why the timeline matters so much—early prep = stronger scores.

How Early Should Your Child Start?

1. For Competitive/Top-Tier Targets: 10–12 Months Before

Schools like Walter Payton, Northside, and Jones require 95th–99th percentile composite scores.

Start a year in advance if:

• Your child wants a top-3 school

• They need to build foundational math skills

• They struggle with test anxiety or pacing

• They tend to procrastinate

What this timeline allows:

• Slow, manageable weekly practice

• Strong content foundation

• Plenty of time for mock exams

• Less stress for your child

2. For Strong Students: 6 Months Before

This is the most common and effective prep timeline.

Start 6 months early if:

• Your child is already above grade level

• They have good study habits

• You want steady improvement without burnout

This timeline allows:

• Content review

• Strategy development

• Regular practice tests

• Time to improve weak areas

3. Minimum Recommended: 3 Months Before

Starting 3 months out is feasible—but tighter.

Best for:

• Students who test well naturally

• Families with busy schedules

• Kids who already score high on NWEA MAP tests

This timeline should focus on:

• Strategies

• Practice tests

• Fixing specific gaps quickly

4. Last-Minute Prep: 2–4 Weeks Before

If you’re coming in late, don’t panic—but expectations need to be realistic.

This timeline works only for:

• Students who already have strong academic foundations

• Kids who need familiarization, not skill-building

Focus on:

• Timed practice

• Reviewing missed questions

• Learning the format

• Building confidence

How to Know if Your Child Should Start Earlier

Your child should start early (9–12 months out) if they:

• Score below the 70th percentile on MAP Math or Reading

• Struggle with reading comprehension

• Are inconsistent test-takers

• Rush or run out of time on exams

• Get anxious on standardized tests

The earlier the start, the lower the pressure.

What Should Studying Look Like?

Months 10–6: Build Foundation

• Review grade-level math

• Build vocabulary

• Strengthen reading endurance

• Begin light practice questions

Months 6–3: Skill & Strategy

• Introduce timed practice

• Weekly practice sets

• Learn test-taking strategies

• Identify weak areas

Months 3–1: Practice Tests

• Full-length mock exams

• Fix mistakes

• Review pacing strategies

Final 2 Weeks: Confidence & Polish

• Light practice

• Focus on errors and timing

• No cramming

How Many Hours Per Week Is Enough?

Recommended weekly time:

• 12 months out: 1–2 hrs/week

• 6 months out: 2–3 hrs/week

• 3 months out: 3–4 hrs/week

• Last month: 4–5 hrs/week (if needed)

Steady beats intense.

Common Mistakes Parents Make

❌ Starting too late
❌ Only doing practice tests and skipping foundational review
❌ Not targeting weaknesses
❌ Ignoring reading comprehension (the most predictive section)
❌ Overloading the child to the point of burnout
