Key Stage 3 caters for school years 7, 8 and 9. 

In the Key Stage 3 department at Ysgol Y Deri we provide an engaging thematic curriculum covering all areas from Routes to Learning to National Curriculum. We ensure that all our pupils make outstanding progress through dynamic and creative learning opportunities, whilst encouraging our students to develop their confidence and self-esteem, as they become young adults.

Teaching focuses on all key areas of the National Curriculum, developing fundamental skills in Literacy, Numeracy and ICT, and through PSE and Life Skills further supporting our students to become confident and caring members of our community.

Our hardworking and dedicated staff provide creative learning opportunities as well as individual programs, which meet the needs of all our pupils and work alongside Speech and Language, and Occupational Therapists and other specialist professionals delivering therapeutic interventions. This will ensure that through collaborative working, our students reach their full potential.

In Key Stage 3 we work closely with the Primary Department to ensure the transition between Primary and Secondary education is an exciting and happy move for the pupils. In Year 9, our transition year, as pupils prepare for the move to Key Stage 4 and the options and qualifications that will be open to them we provide opportunities for the pupils to work with the staff and pupils of the Key Stage 4 department to ensure that each of our pupils embark on a successful, personalised pathway in Key Stage 4.
