I'm currently in a contract, thoroughly fed up and considering leaving to do supply. When I've previously done supply I've early between 90-110 a day (Supply desk and Reed) One agency years ago paid me £120 (Capita). Agencies are so cagey about what rate they will pay you and will only tell you during the interview. Ridiculously I'm told in this area the maximum schools can afford is £110 when the next county pays £120 for the same agency. Sadly it's an hours drive away. My sister does supply in the next county, hence me knowing what she gets paid from the same agency. So... am curious for advice on pay rates and why they vary so much! One agency kept me on the same rate for 5 years but kept charging the schools more each year.
