Chronological Age Chart
Quick-reference chronological age table for test dates in 2026. Shows approximate age in years;months for common birth years. Used by SLPs, psychologists, and educators for Pearson, Brigance, and other standardized assessments.
The table below shows the approximate chronological age for children born between 2013 and 2022, calculated for each month of 2026. Ages are shown in the years;months format commonly used on standardized test protocols. Ages assume a mid-year birth date (July 1) — for exact calculations including the specific day, use our chronological age calculator.

Note: Ages assume a birth date of July 1 for each birth year. Children born earlier in the year will be slightly older, and children born later will be slightly younger. The exact chronological age depends on the specific date of birth and the specific test date. For precise results, use our calculator or the by-hand calculation method.
How to Use This Chart
This chronological age chart is designed as a quick-reference tool for professionals who administer standardized assessments. Here is how to use it effectively:
- Find the child's birth year in the left column of the table.
- Find the test month across the top row (January through December 2026).
- Read the age at the intersection. The format is years;months (e.g., "8;3" means 8 years, 3 months).
- Use the age to quickly identify which age band or norms table to use in your test manual.
This chart is especially useful for:
- Pearson assessments — CELF-5, PLS-5, PPVT-5, EVT-3, GFTA-3, WISC-V, WIAT-4. The years;months format matches the format used on Pearson scoring protocols. For exact Pearson-formatted results, use our Pearson Age Calculator.
- Brigance assessments — Brigance Inventory of Early Development, Brigance Screens. These assessments use chronological age to determine which items to administer and which norms to apply.
- School-based evaluations — Initial evaluations, triennial re-evaluations, and eligibility determinations all require accurate chronological age documentation.
- Planning test sessions — Before meeting with a student, a quick glance at this chart tells you the approximate age you will be working with, helping you prepare the correct test materials and norms tables in advance.
Understanding the Years;Months Format
The years;months format (also written as Y;M) is the standard notation used across most standardized assessments in speech-language pathology, psychology, and education. In this format:
- 8;0 means exactly 8 years, 0 months (the child's 8th birthday)
- 8;6 means 8 years, 6 months
- 8;11 means 8 years, 11 months (one month before turning 9)
Some assessments also include days (e.g., 8;6;15 for 8 years, 6 months, 15 days), but most norms tables only require years and months. The chart above provides the years;months approximation — for the exact age including days, use our chronological age calculator.

| 2012 | 13;6 | 14;5 | 8th Grade |
| 2023 | 2;6 | 3;5 | Pre-K / EI |
| 2024 | 1;6 | 2;5 | Early Intervention |
| 2025 | 0;6 | 1;5 | Early Intervention |
Frequently Asked Questions
Find the child's birth year in the left column, then look across to the column for the month you are testing. The cell shows the approximate chronological age in years and months. For example, if a child was born in 2018 and you are testing in March 2026, find the 2018 row and the Mar 2026 column — the chart shows "8;0" meaning approximately 8 years, 0 months. For exact age including days, use our chronological age calculator.
