The Statewide Data Collection System for Parent Education Programs is an online tool for collecting statewide data on Cornell Cooperative Extension (CCE) parenting education programs. The process of the development and use of this data collection tool are provided as a guide to Extension systems. Results for data entered between March 2009 and July 2010 from participants in CCE parent education programs indicate significant improvements on eight out of 10 measures of parenting attitudes, behaviors, and knowledge, and highlight the value of this online tool for assessing the impact of parent education programs in New York State.
