LENA is making sure Colorado Shines.
You can’t improve what you don’t measure. LENA Grow measures — and improves — the teacher-child interactions that play such a large role in Colorado’s Quality Improvement System.
Even at centers with the highest quality rating, many children experience very little interaction with their teachers. That needs to change. When it does, higher classroom quality follows.
Improving child outcomes, and proving our results.
