Use this sheet to work out the time you will need each year to handle professional communications (email / comms.)
Note: dealing with emails, responding to phonecalls, etc, is not part of your 10% PPA time, though it may be part of a teaching allowance. This calculator is to do with everyday comms to do with classroom teaching. To use it properly don't delete any emails for a week, and then run the calculator based on those figures. To calculate phone call times keep a note in your planner for a week or so of calls and duration.
