This directive will help to:

  • foster good teaching practice
  • encourage positive classroom relationships
  • assist school discipline
  • enhance standards of education
  • retain teaching positions

It should be noted that the Department of Education and Science has no recommended class sizes and there are no legal liabilities on a teacher in relation to this matter. Such liabilities are a matter for the employer who has to ensure that pupils are given an adequate duty of care.

If a school is experiencing a difficulty with regard to the class size directive the School Steward should raise the matter with the Principal and seek a resolution.
