Within the context of a multiple baseline design, the researchers in this investigation used a constant time delay (CTD) procedure to teach two classroom support personnel (i.e., paraprofessional, peer tutor) to use a simultaneous prompting (SP) procedure when teaching a high school student with a moderate intellectual disability to (a) identify words from science core content, (b) identify words from social studies core content, (c) make Kool-Aid, and (d) alphabetize last names by their first letters. The classroom teacher implemented the CTD procedure with a high degree of fidelity, the paraprofessional and the peer tutor implemented the SP procedure with high levels of fidelity, and the student increased his ability to perform the targeted skills.
