Since 1949, EPS has been a leader in developing and publishing programs to help struggling students, including those with dyslexia and other reading difficulties, as well as providing materials that support on-level students so they can continue to meet their goals.
Now called EPS School Specialty, their materials are secular in nature and teach phonics, vocabulary, spelling, and more. Among other things, they're famous for Wordly Wise (first published in 1967) and Explode the Code (first published in 1976). We carry both of these, as well as Vocabulary from Classical Roots, SpellWell, Analogies, MegaWords, Primary Phonics, and a number of other materials.
