Background: Am being considered for a long term supply (at least a term, maybe more) teaching my subject in a nice small Catholic secondary school. Me and two others being considered - went in for informal chat the other day, felt it went well, got feedback via agency that they were very impressed with me - all well and good so far. Teacher I would be replacing is off ill with 'stress' so they have been struggling for cover since he disappeared. I am to go in for a day in January for a more formal interview. Fair enough - they need a more formal interview and observation - but I have received my "itinerary" from the agency today: Period 1: Yr 7 - this will be observed by the Deputy Head and their PGCE student (????? why am I being observed by a PGCE student?) Period 2: Yr 8 - would usually be taught by the PGCE student but I am to do a pre-planned cover lesson as if I were on supply. Why?? Period 3: Yr 7 - Same planned lesson as lesson 1 but I won't be observed. Um - again, why? Surely this is just unpaid cover!!! Period 4: Free - yay, I get to talk with PGCE student and Deputy Head Period 5: Observation of Yr 11 GCSE lesson with PGCE student so I get to know them and where they are up to - great - this will be useful. Periods 1 and 5 I have no problems with, but surely they are just using me as a supply teacher in Periods 2 and 3. I have replied to the agency to this effect, although a little more diplomatic, but basically asking if I am getting paid for the lessons they are using me as cover. But I do really want this job so don't really want to rock the boat at this stage. WWYD?
