Frequently asked questions
What does this promotion timing calculator do for Cover Supervisor?
It compares total gross earnings over a chosen period depending on when you are promoted, using typical pay for Support (NJC SCP 5–12) and higher bands in School Teachers' Pay (England). One scenario promotes sooner; the other later. Optional second promotion step included.
How should Cover Supervisor staff use this at Schools?
Use it to see the financial shape of "promote now" vs "wait a few years" before you factor in non-pay reasons (workload, training, location). Promotion still depends on vacancies and Schools policy.
Does it use Support (NJC SCP 5–12) pay from School Teachers' Pay (England)?
Yes. We start from illustrative pay on Support (NJC SCP 5–12) and move to the band you select after promotion. Spine points and increments follow the dataset; your actual pay point may differ.
Why can the earnings gap look large?
Higher bands pay more each year; over ten years small annual gaps compound. Real timelines include pay awards, part-time working and stepped progression. Treat the delta as a rough comparison.
Can I model two promotions for Cover Supervisor?
Yes. Turn on the second promotion option and set the year and target band. Useful for roles with clear progression routes (for example Support (NJC SCP 5–12) to the next band and beyond).
What does "years already in this band" mean?
It sets your starting salary on Support (NJC SCP 5–12) before any promotion in the model. If you have been on the band for three years, you are likely higher on the spine than someone in year zero.
Where can Cover Supervisor staff check official pay?
See gov.uk STPCD, your school or the NEU for current rates and how promotion affects pay in School Teachers' Pay and Conditions (STPCD) or NJC for support staff.
