The State of Florida and local mandates require that a diagnostic/prescriptive systems approach to reading and mathematics instruction be available to all students at grade levels K-6. It has been demonstrated that the Dade County Systems approaches are viable alternatives to non-systems approaches to reading and/or mathematics instruction. Results of the study of second and third year participation in Dade's Systems programs provide clear evidence that: (1) participants performed better the longer they were in the programs, and (2) after a second year in the program the percentages of communication and mathematics skill items answered correctly on the Florida State Assessment Test was higher than the percentages achieved by non-systems pupils. This held true for all categories of objectives and the total as well. Participants of the High Intensity Reading Program, on the other hand, have for the second year, demonstrated negative results in reading comprehension and communication skills tests. Consequently, Dade Systems programs are recognized as a more beneficial mode for delivering basic skills instruction than non-systems programs and are unequivocally recommended as appropriate diagnostic/prescriptive programs into which to phase non-systems pupils.
