Presented is the Marshalltown Behavioral Prescription Guide for communication which consists of incremental behavioral objectives and strategies to aid parents in the prescriptive teaching of preschool handicapped and culturally deprived infants and children. The guide is intended for use prior to a weekly home visit resulting in a weekly prescription left in the home. Parents are said to go through a 6 hour orientation course to allow them to introduce the management procedures and chart the progress of the child with the long range goal of helping them use the program materials directly. Each of the 93 profile items are presented individually in terms of profile number, behavioral definition, cue/s, measurement criteria, materials needed, and behavioral objectives and strategies. Sample prescription forms are also included. The following are examples of profile items: produces vowel sounds, responds to "no" by stopping activity, consistent use of three or more words, combines words into simple sentences, uses own name in reference to self, matches colors, carries out four individual commands using prepositions, recites the numers to thirty, prints name, and identifies preceding and following day for specified day of week.
