º¬Ðß²ÝÊÓƵ CKLA & º¬Ðß²ÝÊÓƵ Caminos
Using a fundamentally different approach to language arts, º¬Ðß²ÝÊÓƵ Core Knowledge Language Arts® (CKLA) is built on decades of early literacy research that demonstrates the importance of wide-ranging background knowledge and explicit and systematic instruction in foundational skills. Increasingly more districts are choosing º¬Ðß²ÝÊÓƵ CKLA because they know they’ll see results.
º¬Ðß²ÝÊÓƵ CKLA meets the criteria for Tier I-Strong Evidence as an education intervention under ESSA.
