Pearson Age Calculator Discontinued: Best Free Alternatives in 2026

If you administer Pearson assessments like WISC-V, WIAT-4, WPPSI-IV, or Bayley Scales, you know that exact chronological age in years, months, and days is required for valid scoring. For years, Pearson provided an official age calculator on their website. That tool is now gone. Here's what happened and where to find the best replacement.

The Official Announcement

Pearson Assessments has discontinued their live age calculator. On their campaign page, they state: "We no longer have a live age calculator on our site." The page remains online at pearsonassessments.com, but the calculator itself has been removed. Pearson now directs users to third-party tools for chronological age calculation.

Impact on Practitioners

School psychologists, educational diagnosticians, speech-language pathologists, and special education professionals rely on exact chronological age when administering Pearson tests. Norm tables for WISC-V, WIAT-4, Bayley-4, and other assessments are keyed to age in years, months, and days. Using an approximate age or rounding to the nearest month can lead to incorrect standard scores, percentile ranks, or age equivalents—which in turn affects eligibility decisions and intervention planning.

The discontinuation means practitioners must find an alternative. Pearson no longer offers the tool, so any accurate chronological age calculator that follows the standard year-month-day method is acceptable for test administration.

What Pearson Recommends: TimeAndDate.com

Pearson now links to TimeAndDate.com's duration calculator. It's a general-purpose tool that calculates the time between two dates. It works, but it has limitations for assessment use:

  • No total months output — Many assessment protocols need total months (e.g., for age bands or norm lookups). TimeAndDate shows years, months, days, but you must compute total months yourself.
  • Generic interface — Designed for general date math, not for assessment workflows. No quick-copy format optimized for protocols.
  • Ads — The free version includes advertisements, which can be distracting during testing sessions.

If you need a quick calculation and don't mind the limitations, TimeAndDate.com is a valid option. But for practitioners who want an assessment-focused tool with total months, mobile-friendly design, and no ads, alternatives exist.

Best Free Alternative: Purpose-Built for Assessments

A purpose-built chronological age calculator for Pearson assessments should:

  • Use the same year-month-day calculation method as Pearson's former tool
  • Display total months automatically
  • Work well on mobile (tablets, phones) for in-session use
  • Require no registration or signup
  • Allow one-click copy of results for protocols
  • Be ad-free

Our free chronological age calculator meets these criteria. It follows the standard subtraction method used by Pearson assessments, shows years, months, days, and total months, and is built for WISC-V, WIAT-4, Bayley-4, and all Pearson clinical assessments. No account required—enter birth date and test date, get the exact age, copy to your protocol.

Conclusion

Pearson's decision to discontinue their age calculator leaves practitioners in need of a reliable alternative. TimeAndDate.com is the option Pearson links to, but it's a general tool. For school psychologists, SLPs, and special education professionals who want an assessment-specific calculator with total months, copy support, and a clean interface, a purpose-built alternative is the better choice.
