I'm interested in how many schools are using unqualified staff to teach. I've just finished supply in a secondary school and am horrified to find that no one in the IT dept who was teaching had QTS (or even a degree). They had apparently 'worked in industry'. 1 TA teaching 7 periods of Maths a week at KS3. 1 TA teaching 8 periods of English a week at KS3. 1 TA teaching French for 8 periods and also History for 3 periods. None of these TAs were qualified at all - none even had A levels in the subjects, never mind degree. Outside CS brought in for 4 weeks to cover for Head of Maths - he was relative of SMT and had a degree - in Geog. No QTS though. Is this legal? And how common is it please? I am so shocked. How is this Head getting away with this? No wonder so many of us are struggling for work. I've taught for over 20 years and can't believe this is possible.
