G&T - an 'accolade' or an additional educational need

[oneofsuesylvesterscheerios]

If a student is on the G&T register for lots of subjects at secondary school, when they get a new teacher at the start of the new school year, should that teacher see this as an accolade for the student and assume they can attain top level marks/grades automatically and so set the highest level work?

Or should the teacher initially set work that is appropriate for a number of abilities and wait to see if the student responds with work that is noticeably higher in attainment before closer differentiation takes place?

In other words, should the biggest level of effort come initially from the teacher, anticipating fantastic work, or from the student, putting their best effort into demonstrating what their capabilities are?

Paragraph 2 sounds like a lot of wasted work in many cases.
Only a Box-ticking exercise, anyway.

ime a lot of the work in Yr 7 is of a kind that can be done to different standards anyway: lots of project work, essay writing etc- so the same work can be set for a wide range of students and get widely different results, nothing to stop an able student writing undergraduate quality essays or do technology work to a professional standard

I suppose the only real exception would be maths, but then again it should be quite easy for a gifted student to demonstrate giftedness in maths
