Do you have a reduced timetable? This should be 10% PPA time like everyone else, plus and further 10% for NQT time (can be used for observation, training or just geting on with your own work. If you do not have a mentor, contact your LA and tell them. There is someone at the LA who is responsible for NQTs. A mentor is a legal requirement for NQTs. Have you had observations and all the necessary paperwork completed? Perhaps try contacting your union for advice on how to proceed.
