## I want to do this:
As the newly formed London board, we wanted to change the way the tracks are implemented. We feel that having tracks after the Full Stack course with a duration of 5 weeks would clarify the expectations and objectives of the tracks as well as relieving the pressure put on the program managers.

## Here’s why I want to do it:
Tracks are always a confusing moment for the trainees and volunteers. It produces a lot of stress for everyone in the community, stretches resources and results on trainees dropping out.

## Here’s how it serves our goals:
Getting everyone to do the full stack course will help trainees and CYF identify their strengths and weaknesses more objectively. Having a tests before getting into the tracks and final project is improving our chances of higher employment at the end of the course and limiting frustration during final projects.

## This is how much time I can put towards this change:
We are ready to support CYF staff to implement any changes required.

## This is the help I need from others to get this done (if any):
Feedback on the solution (such as the checkpoint test) and communication.
