It allows schools to develop. In my constituency, I can think of one primary school in the village where I lived, Maghaberry, where we moved from a seven-class base school. Enrolment was increasing as the population grew, and we had to move to providing composite classes. That was the only way to allow the school to continue to grow. As populations grow, you want to move to having two class bases in a school. Composite classes have a role where it meets the need of a local population.
