Zone of Proximal Development (ZPD)

The Zone of Proximal Development (ZPD) suggests the readability-level range from which a student should be selecting books for optimal growth in reading without frustration. The Zone of Proximal Development is especially useful for students using Accelerated Reader.

The Zone of Proximal Development, however, is approximate. Success at any level also depends on the student's interest and prior knowledge of a book's content. Teachers should use their professional judgment to adjust the level of books read to match an individual student's needs and interests.

The Zone of Proximal Development is included on the Annual Progress Report, the Diagnostic Report, the Growth Report, the Reading Range Report, the Screening Report, the Student Progress Monitoring Report, the Summary Report and the Test Record Report.
