I know this is an old thread, but I volunteer with a local school to assist on their D of E Bronze practice and assessed expeditions. I have no special skills, but have done this for the last 10 years and love it.
The school does practice 2 days & the assessed 3 weeks later.
They work on map reading and route planning in advance.
The practice then takes place on Thursday & Friday as this encourages kids to get involved ,& also helps in getting staff
On the Thursday, they have a half day of workshops - putting tents up & taking them down, countryside code, 1st aid & cooking.
For the remainder of the day they have a 3hour guided walk with no bags.
On the Friday, they are then given a route to walk which they do with bags and with staff at checkpoints to keep them on track.
They then do the assessed 3 weeks laterat a different location.
It works well for the most part. In the last 3 years, we have had an average of 70 students each year.
Equipment can be hired for any number of items at £30. If anyone has genuine financial difficulties, the school can waive the fees or funds can be claimed from the D of E hardship fund.
We aren't perfect, but we try our best.
