Purpose In this reply, we respond to comments on our article “Tracking the Growth of Tense and Agreement in Children With Specific Language Impairment: Differences Between Measures of Accuracy, Diversity, and Productivity.”

Conclusion The finite verb morphology composite can be disproportionately affected by frequently occurring grammatical forms produced through direct activation. This assumption was one of the reasons we wished to compare this measure to the tense marker total and the tense/agreement productivity score. The latter two measures provide valuable developmental information that is not available from the finite morphology composite. Yet, the finite verb morphology composite shows good diagnostic accuracy and an interpretable pattern of growth and is relatively stable across different sample sizes.
