“CELF is doing really important work and I think that teachers are hungry for the kinds of support that CELF can deliver. At the beginning, a number of teachers don't have a lot of familiarity with some of these really important concepts. But afterwards, we see consistently that the teachers report high levels of confidence and comfort with their knowledge of the subject and also their comfort in teaching these concepts in the classroom.”
