How often does a student need lessons?
When working with a small group of students in a school setting, five times a week is best. If the goal is to close the gap, intensive focus and frequent opportunities to practice are required. If students are working after school, two or three times a week may be the best that can be arranged. Fatigue and activities are factors in after-school schedules. Once a week is not enough, because it requires students to hold on to new learning for 7 days without review.
