48. Should You Assess Grammatical Morphemes at Age 3? The Evidence Says No.

Are you assessing grammatical morphemes in your three-year-olds? You may want to rethink that approach. In this episode, I break down three evidence-based reasons why grammatical morphemes are not reliable indicators of language development at age three.

We’ll dig into:
 ✅ Why normative data is lacking
 ✅ Why variability is too great at age three
 ✅ Why standardized tests like the SPELT-P2 produce over 80% false positives

Instead of wasting time on unreliable measures, I’ll share what to focus on so your evaluations are both accurate and ethical.
