It may also be helpful to visit the National Centre for Excellence in Teaching in Mathematics (NCETM) for Self-evaluation Tools. The National Centre for Excellence in the Teaching of Mathematics (NCETM) aims to meet the professional aspirations and needs of all teachers of mathematics and realise the potential of learners through a sustainable national infrastructure for mathematics-specific continuing professional development (CPD).

Their portal, www.ncetm.org.uk provides a wealth of resources, sources and tools for professional development to support all teachers of mathematics.

One element of the portal which you may find particularly helpful is the NCETM Mathematics Teaching Self-Evaluation Tools which we also reference in the
Useful Links section.
