Parental investment is critical to our success. We simply cannot educate scholars without parents. Your job as a teacher and an advisor is to insist that scholars are at school on time and in uniform, with their reading log and homework done. Their conduct needs to be stellar at school and outside of school. Parents must also be super responsive.
If parents are not fulfilling their responsibilities, you must meet with them. If you are still not successful, manage up to your leader.
