TOLD-I:5 Age Calculator

The TOLD-I:5 continues the TOLD framework into the intermediate and secondary years, where language demands shift toward syntax and abstract vocabulary. It overlaps the TOLD-P:5 at age 8, so the recorded age decides which form is correct.

Enter the exact chronological age in years;months.days. Scoring selects the norm table containing that age, so the partial month is not rounded up.

The underlying calculation is the same for every instrument — complete years, complete months, then the leftover days. What differs is which part of it goes on the form. The calculator above reports all four figures at once, so you can copy the one the TOLD-I:5 manual asks for without recalculating:

• Years;months.days — the full record-form format, e.g. 9;6.20
• Years;months — complete units only, e.g. 9;6
• Complete months — e.g. 114 months
• Rounded to nearest month — e.g. 115 months (9;7), using the 15-day threshold

The exact date arithmetic, including month-end clamping and leap-day handling, is documented in the calculation methodology.

A child born February 26, 2017 and assessed on September 15, 2026:

• Chronological age: 9 years, 6 months, 20 days
• Record on the TOLD-I:5 as: 9;6.20
• Day remainder: 20 days — 15 or more, so a nearest-month rounding rounds up

Enter these exact dates above to reproduce the result. Every figure on this page is computed by the same library that runs the calculator, so the worked example and the tool can never disagree.

Same calculation, different recording format. These are the instruments most often administered alongside the TOLD-I:5:

The full list is on the assessment instrument reference, and the assessment age calculator covers any instrument not listed individually.
