Teaching children to read is a complicated process. Children begin school at varying levels of ability, yet are all required to meet a set standard of achievement. It is up to teachers to assess each student, identify individual learning needs, and provide support. A motivating, literacy-rich program that includes whole-class, small-group, and individualized instruction is beneficial to struggling readers. Scripted and non-scripted literacy programs have proven to be effective, but it is the teacher who has the greatest effect on student success.
