This resource guide provides a set of assessment instruments to help the adult basic education teacher appropriately place each learner at Level I, Level II, and/or General Education Development Level of instruction. An introduction briefly describes instruments and suggests examples of implementation. A teacher's guide contains general directions for using the three assessments, which follow. Section A (Level I) deals with the learner who has little or no academic skill. It makes assessment of basic readiness skills in reading, language, and mathematics. Section B (Level II) measures decoding skills and attempts to determine indepth knowledge of the discipline and ability to make critical judgment and to use problem-solving techniques. Section E (Level III) assesses more indepth knowledge of the disciplines to determine whether the learner has knowledge to the level of successful completion of requirements for a high school equivalency certificate. Answer keys are provided. Appendixes include ideas to consider (diagnostic-prescriptive instruction, Dale's Cone of Experience, writing instructional objectives, selecting activities and materials, daily lesson planning, daily evaluation of learner's progress); useful techniques, such as VAK (visual, auditory, kinesthetic), VAKT (visual, auditory, kinesthetic, tactile imagery), and word box; and interest and attitude inventories.
