Welcome to the LETRS Family

LETRS Prepares Teachers to Deliver Quality Instruction

Today, teachers graduate with little preparation for how to teach reading and literacy development effectively. Yet, research demonstrates that approximately one-third of students nationally cannot read at even “basic” levels. Of those who cannot, most will not read without proper instruction.

Make an impact in your district today. The LETRS family of products, which includes LETRS, LETRS for Early Childhood Educators, LETRS Classic, and A Principals' Primer for Raising Reading Achievement, is designed to help you increase literacy skills, change reading outcomes, and set students on a lifelong path to success.
