How might data be collected for this target response?Observe times, continue to check data sheets
Identify several interventions that might help improve response rates. Place them in order with the least-restrictive at the top so that the interventions may be introduced systematically, adding more restrictive / less favorable interventions after the outcomes of less restrictive options have been measured.

Spend more time observing sessions, give reminders, post reminders around the program, provide reinforcement for completing tasks
