Collecting children from school early

We fully understand and support the fact that from time to time parents have to collect their children earlier from school due to medical appointments. Or other exceptional circumstance. We respectfully request that if appointments can be arranged out of school hours, that parents do. However if it is unavoidable please write a wee note to the class teacher in the morning to let her know that your child will be collected earlier and your child will be ready. Thank you so much in anticipation of your understanding in this matter
