The purpose of this document is to suggest an assessment/prescriptive/instructional (API) process for working with older learners experiencing reading difficulties. Following a justification for the designing of materials specifically for older learners, the document explains how to collect data about learner's interests, attitudes, and reading abilities and how to interpret test data. A sample personal data form and a list of criteria for measures analysis are provided. The document then indicates procedural steps for the API process for both learners and instructors. An appendix describes the following assessment measures found useful for the API process: the Reading Miscue Inventory; the Stanford Diagnostic Reading Test, Level III; the Carver-Darby Chunked Reading Test; Informal Assessment Inventories; and cloze techniques. The appendix also lists and annotates 22 publications helpful for students, provides a sample prescription for an older learner, explains useful study techniques, and shows how to use cloze and reciprocal questioning procedures as approaches to intruction.
