All students have an essential skills self-assessment tool in their planners. Students use this resource to reflect on their essential skills targets and areas for development. In addition, many tutors have been using the Hub group-level assessment tool to identify resources to use with their classes. Next year we would like to make this assessment cycle more consistent. We underook a through evaluation of our first challenge day, by sending a survey out to staff and students. This helped us to monitor the impact of the Challenge Day; we used the feedback to improve future Challenge Days. A large majority of students enjoyed the day, many (between 50% and 39%) rating it 'very good' or 'fantastic'. Different year group learnt different things about their skills, but encouragingly all year groups gave a high rating for learning 'how to improve their skills' For all three groups the opening sessions were not as popular with the latter sessions. This may be because these were new challenges for them which took time for them to understand. Most Year 7s & 9s enjoyed all the sessions (never less than 60%, for Year 8s it was never less than 50%) Comments on how to improve the day were most commonly about being more practical and active across the Year groups
