This document, eighth in a series of 11 subvolumes of a handbook prepared to provide training for educational research and development personnel in the development of instructional materials, deals with the task of planning accommodation of individual differences. The document is organized according to the two sequential steps involved in performing the task. Step 1, planning the use of accommodation techniques to be uniformly applied to all members of the target population, involves identifying administrative and instructional techniques. Step 2, planning the use of accommodation techniques to be applied uniformly to subpopulations or variably to ndividual students, involves identifying techniques to specifically accommodate subpopulations and individuals. Background information covers: (a) individual differences that need to be accommodated; (b) major ways to accommodate individual differences; (c) learner-selected vs. trainer-selected methods of accommodating individual differences; (d) accommodating a total population vs. subpopulations vs. individuals; and (e) differences in the ways accommodation occurs for a total population vs. subpopulations vs. individuals.
