PreK – Kindergarten Guide

These are the foundation years. The good news: the skills that predict later success — language, sounds, counting, self-control — are all teachable, and playful home routines genuinely move them.

Ages: 3–6 years. Every child develops at their own pace — this guide shows what research says helps, what your school should be doing, and the signs that mean "ask for a formal evaluation now."

Common struggles at this level

Speech and language delay: late talking, hard to understand, small vocabulary, trouble following directions.
Weak early literacy: not noticing sounds in words, few letter names or sounds — risk factors for later reading disability (dyslexia is a language-based reading disability; it is not about intelligence).
Weak early numeracy: counting without understanding quantity, no sense of 'more/less,' patterns, or shapes.
Self-regulation struggles: big tantrums, trouble waiting, sharing, or joining play.
Motor or play delays: holding a pencil, cutting, hopping, pretend play.

Techniques with the strongest evidence

Intentional social-emotional teaching Strong

Teach feelings, turn-taking, and calming skills on purpose, in short lessons with practice — not just by correcting behavior. (IES, Preparing Young Children for School, 2022)

Shared book reading Strong

Read together daily, talk about the pictures and words, ask questions, and re-read favorites. (IES, 2022)

Letters and sounds Strong

Play with the sounds in words first (rhymes, first sounds), then teach letter names and sounds explicitly, with practice. (IES, 2022)

Intentional math teaching Strong

Small-group, sequenced teaching of number, geometry, measurement, and patterns — at least 15–20 minutes nearly every day in preschool programs. (IES, 2022)

Executive-function games Moderate

Games and routines that practice stopping, remembering, and planning — freeze games, Simon Says, sorting and memory games. (IES, 2022)

Parent–Child Interaction Therapy (PCIT), ages ~2–7 Strong

For disruptive behavior: a therapist coaches the parent live during play and discipline. A meta-analysis of 23 studies (1,144 children) found a large reduction in acting-out behavior (SMD about −0.87) and lower parent stress.

What schools do (MTSS)

Most US public schools use MTSS — a Multi-Tiered System of Supports. Tier 1 = good teaching for everyone, plus short screening checks for all students 2–3 times a year. Tier 2 = extra small-group help for students flagged at risk. Tier 3 = intensive, often 1-to-1 help from a specialist. Tiers describe a level of support, not a label — your child can get Tier 2 or 3 help without any diagnosis or IEP.

Universal screening for reading and math readiness in fall, winter, and spring.
Tier 2 small groups for sounds, letters, and counting; Tier 3 intensive help. In the IES model, foundational-skills groups meet 3–5 times a week for 20–40 minutes.
Under age 3, help comes from IDEA Part C early intervention (home-based, free or low-cost). Ages 3–5, preschool special education comes through your school district under IDEA Part B — even if your child is not in public school. That duty is Child Find.

What you can do at home

Read aloud 10–15 minutes daily. Point to words and pictures, ask 'what happens next?', and let your child 'read' a favorite page back to you.
Sound games in the car: rhymes, 'what sound does sun start with?', clapping syllables.
Count real things — stairs, spoons, socks. Compare 'more/fewer,' sort by color and size, name shapes while cooking and building.
Name feelings, keep a predictable routine, and give specific praise ('You waited for your turn — that was hard') far more often than correction.
Choose talk, play, and books over passive screen time; chat with your child through everyday routines.

⚠️ Warning signs — ask for a formal evaluation if:

By 18 months–2 years: few or no words, loss of words or skills at any age, not pointing to show you things, not responding to their name. Check the CDC milestones in our Milestone Checker.
By age 4–5: speech strangers mostly cannot understand, cannot tell a simple story, cannot recognize any letters or count a small set of objects.
Extreme difficulty with routines and transitions, or behavior that regularly prevents joining preschool activities.
Never 'wait and see' about skill loss (regression) — act promptly. You can refer your own child: Part C under 3, the school district at 3+. No doctor's referral needed.

How to ask: put it in writing. Our free Evaluation Letter Generator writes the letter for you, and the Know Your Rights page explains the 60-day timeline and why a school cannot make your child "finish interventions first."
