Questions to ask before they go
1. What's the contact number/address?The teacher should have a mobile phone on them.
2. What time will you get there/come back?Organise a telephone tree (a system for parents phoning other parents) so you'll know when the group has arrived or be informed of delays.
3. What is the staff-to-pupil ratio?The Department of Education gives these guidelines:
Under-fives: more than one teacher (no specific number stated) to six pupils.
Years One to Three: one teacher per six pupils.
Years Four to Six: one per 10 to 15 pupils.
Year Seven upwards: one per 15 to 20 pupils.
