Designed specifically for language-delayed teenagers and adults, each of
the nine STEP workbooks can be used independently or as part of the
series. The sentences, stories, and illustrations are high-interest; the
reading level is third-to-fourth grade. The workbooks are
self-instructional and work equally well in a classroom setting or in an
independent study program.
