Our organization would like to set up errorless teaching strategies that fade out interventions systematically as clients demonstrate mastery criteria of responding. (i.e. fading out prompts/ supports as mastery is met in each phase, phase lines auto dropped between intervention phases, until moving to generalization phase, and mastery phases).

This set up requires the ability to have different prompts available in different intervention phases and different prompts scored as correct/ incorrect in different phases (i.e. a Most to Least Intervention may have several phases of intervention with errorless prompts scored as correct, fading to an independent phase with no prompts; Constant Time Delay requires 2 intervention phases: 0 sec delay phase and delay phase).
