"It is possible to get these boys back on track, but you have to be organised and determined, and have their parents' support.
"I would put all the email addresses of the boy's teachers on a group sending list, and have his parents' phone number next to the phone in my department office and a copy of his timetable in my planner. The boy's planner would be physically attached to his blazer with a ski-clip.
"Put him on a report, asking his teachers if he has done his homework, remembered his book, and written his homework down in his planner. Get him to see you at the end of every day with his report. Set targets with him, and explain that if the average target is not met, then the week will be repeated. The danger, of course, is that he 'forgets' to report to you at the end of every day. In the past, I have phoned home, or collected the boy from his last lesson, or sent someone to escort him.
"List the homework he has to complete that night. Check it in the morning.
If it is not done, get him to come and do it at lunchtime.
"It can be exhausting for the first few days as the boy will constantly test boundaries to see if you are serious. Consistency is the key. This type of boy does not miraculously become organised overnight, but he can improve."
