Community Science worked with the Choice Program to develop and implement systems to facilitate data-based decision-making by all program staff, and evaluated the extent to which the Choice Program reduced problem behavior. Community Science also provided an independent assessment of the Choice Refocus & Opportunity (R & O) program during its first year of implementation (October 2006 to October 2007). Specifically, the evaluation examined the extent to which the program was implemented as intended and the extent to which the program reduced participants’ problem behavior. (2005-2007)
