Well, it will essentially be how you are going to deliver that.
Examples of promoting:
Reminders on school Twitter feed or school facebook
Certificates/credits/badges* for attendees
Posters/noticeboard
Form tutor message/timetable on PowerPoint reminder in form time
Timetable of activities on school website
Free biccies/juice* for attendees
Monitoring attendance/numbers/take up
Extras e.g. Writing competitions, bake offs, charity days*
Linking in with their careers soft skills (secondary)
Workshops/drop ins (secondary)
It depends on how many departments already run a club...if many do, it is collating it all in an easy snapshot. What Where Which year groups
Including sports training, fixtures etcetera
You would want to bring in Every Pupil matters/inclusion
You would want to bring in Culture Capital
As to how formal, depends on number of internal candidates
Could just be a chat, if only you applying
It could be a quick tick box exercise
Why are you interested
How will you approach role/implement
How will you ensure accessibility to all
Safeguarding question
Only difficulty is if you have no staff doing stuff already, nothing up and running, no budget or resources and no-one you can strong arm
How will you persuade volunteers? Are your extra curricular pre school, break, lunch or after school?
Are you primary or secondary?
Do you have parents who can get their clearance, share skills or run something
Do you have any outside crafters who could run courses at a price/outside scienctist courses coming in
