This should be resisted.
You can only be held accountable for things that are directly within your control as a teacher.
Pupil data and class data is not an appropriate target.
Some KEY QUOTES
• School and trust leaders should not make pay progression for teachers’ dependent on quantitative assessment metrics, such as test outcomes, or
• Set targets for teachers that are outside their control. Targets should be closely tied to genuinely actionable behaviours, that are aspirational yet achievable.
• Assessments are designed to evaluate, measure and report the progress and attainment of pupils, rather than evaluate the performance of teachers.
