The growing tuition industry costs parents millions of dollars and also raises questions about the quality of teaching in our schools ("Super tutors in demand/Each of them earns at least $1m a year"; Monday).

What makes a "super tutor" so super? Is it the way he teaches or is it the result of clever marketing and/or the pre-selection of students?

If it is due to superior teaching methods, perhaps the Ministry of Education and principals should emulate these tutors and change the way certain subjects are taught.

The "value add" provided by these tutors cannot be a result of greater individual attention, since their class sizes can be as large as 30 to 40 students.
