As I said in my initial answer, class sizes are falling; they have been falling consistently for some time, and they will fall further. Michael McMahon's second point was also correct. Parents in Scotland would be aghast if teachers were to go on strike when class sizes are falling; when further class size reductions are planned; when there are more adults in Scottish classrooms than there have ever been; when there are more support staff in schools; when there is the best pupil to teacher ratio that there has been for many years, if not at any time; when teachers' class contact time with their pupils is being reduced; when there is more time for preparation and marking in our schools; when there is more time for continuing professional development; and when we are recruiting more teachers.
