Homework Help and the Lower Grades?

Beginning in November a test program was initiated with the junior high students called, "homework help". This program has been based off of similar programs at Holy Family Catholic School and local area public schools. The goal of the program is to increase student achievment by decreasing the amount of late and missing homework assignments. The program operates by increasing school - parent communication and student accountability. In practice when a child fails to present their assignment they are sent to the office to notify their parent and are expected to either stay after school that day or the next to complete the missing work. So far the program was had solid success in the Junior High. We are considering rolling this program out the to 3rd through 5th grade at the start of the next semester in mid-January. We would love to hear your thoughts.
