When choosing a preschool for your child a key question to ask is the turnover rate of the staff. Often preschool is seen as a temporary placement by teachers and ECE professionals, and turnover is often over 30%, meaning there is little continuity in vision or teaching methods from year to year.
Most preschools have very set drop off and pick up times. It is the obligation of the parents to ensure that their child is dropped off and picked up during these scheduled times. Most preschools do not have the option of providing early drop off or late pick up, and this needs to be address at the initial interview if it may become a problem for the parent and school.
