After a lot of soul searching, I have made the decision to leave my post and leave teaching. I am a good teacher (so I'm told!) and have had some amazing experiences to date but I need to make a change. I do not make decisions lightly and this has been a while coming. I am looking for help about the dates that I need to put in my letter of resignation. I want to leave at the end of the Spring term which, for my school, is 29th March and they return on 10th April. Would I put the 29th March or 10th April? I'm just not sure if I put the last teaching date or last date of term. Thank you in advance for your help!
