Will be graduating from NIE PGDE next year.

Would like to check that for a Teaching Scholar (Local),
(a) What is the starting CEP?
(b) Average years to reach each substantive grade (GEO 3, 4, 5, etc.)
(c) Will school accord greater opportunities / exposure (higher stake), even for BTs?
(d) Any other advice to boost Performance grade / CEP / maximize career growth.
