Key Stage 3 runs for Years 7 and 8.

Students learn Science for 3 hours per week at Key Stage 3.

In that time students will study 20 topics – details of which can be found on the individual year-group Science pages.

The 20 topics are spread evenly among the three disciplines of Biology, Chemistry and Physics. Embedded within the topics are How Science Works skills that develop Students’ practical ability and understanding. Students sit a short test at the end of each topic.

In Key Stage 3 Students are expected to do 20-30 minutes of independent learning (homework) per week.

In Year 7 Students learn in their mixed ability Tutor groups.

In Year 8 Students are divided into three bands (w, x and y). Each band has top set numbered ‘1’ and two mixed ability sets numbered ‘2 ‘ and ‘3’.

In June of Year 8 Students will sit a final exam. The level from this exam will assess progress through Key Stage 3 as well determine the appropriate groupings for Key Stage 4.

In KS4 Students are divided into 2 bands (x and y). In the ‘x’ band students are set from 1 to 5 and in the ‘y’ band they are set from 1 to 6.
