In an effort to identify the characteristics of incoming high school students who are most vulnerable to dropping out, the research staff gathered data on the senior students at the end of the school year.
Based on this data, freshmen who are identified as vulnerable to dropping out will be offered access to free comprehensive tutorial services.
