Materials in the Initial Teaching Alphabet (ITA) were developed for use in remedial reading instruction of functionally illiterate adults. These materials were used for an experimental tutorial session totalling 20 hours of instruction and two hours of testing and interviewing. The tutorial sessions provided a case study for use in formative evaluation; an outline for a full summative evaluation is also included. The study concludes that ITA can be useful as an instructional medium for functionally illiterate adults, especially those with negligible or minimal reading skill levels. (Author/AA)
