The purpose of the study was to evaluate the effects of a system of least prompts procedure and use of a graphic organizer to teach an academic standard for elementary students with moderate intellectual disabilities. A multiple probe (days) across participants design was used to evaluate the effectiveness of using a system of least prompts and a graphic organizer to teach students how to compare two characters from adapted text. The results showed a system of least prompts and the use of graphic organizer was effective in teaching an academic standard for students with moderate intellectual disabilities.

Constant time delay (CTD) and progressive time delay (PTD) are both evidence-based practices used to teach students with intellectual disability (ID). The prompt delay strategies have been used for instruction with academics, social, vocational, and communication skills. There is limited research regarding the differential effectiveness of the time delay variations for teaching academic content to students with ID. The present study compares the effects of CTD and PTD in the acquisition of academic content with four students with ID. An adapted alternating treatments design was used to compare the effectiveness and efficiency of the two procedures. Generalization was assessed across settings, participants, and materials. Results indicated that both strategies were effective but PTD was more efficient in regards to number of errors and average time to criterion.
