Guide for Teaching Assistant
This guide helps Teaching Assistant at Schools compare promotion timing scenarios from Support (NJC SCP 5–12). The calculator shows gross earnings only; promotion still depends on vacancies, funding and employer policy.
Why promotion timing matters for Teaching Assistant
Moving to a higher band or grade earlier means more years at the higher rate. Over five or ten years the cumulative difference can be substantial, even when the step from Support (NJC SCP 5–12) to the next band looks modest year to year. This tool compares gross earnings under two promotion timings using illustrative pay from School Teachers' Pay (England).
Typical progression for Teaching Assistant
Common routes: TA → HLTA or teacher training. Use the calculator below to see how pay changes over time on school support staff scales.
What to compare in the calculator
Set your current band (Support (NJC SCP 5–12)), years already in band, and how far ahead to project. Choose when the first promotion happens in each scenario and the target band after promotion. Optionally add a second promotion step for longer career routes.
Real world factors
Promotion depends on vacancies, performance, funding and policy. The calculator does not model competition for posts or time to complete training. Use it for financial comparison alongside career planning conversations with your line manager or union.

Frequently asked questions
What does this promotion timing calculator do for Teaching Assistant?
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 Teaching Assistant 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 Teaching Assistant?
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 Teaching Assistant 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.

Are these figures official for Teaching Assistant?
No. All outputs are illustrative planning aids. Always check Schools, your union, regulator or official published terms for definitive amounts and rules.
