A student teacher decided to carry out some observations in two schools, one, an oversubscribed school in an affluent area, the other, an undersubscribed school in a less affluent part of town. She was expecting to find the first school the easier option to work in.The oversubscribed school had a slightly higher value addedIf a school adds value, it means that it has managed to support its students in reaching a higher grade than they were originally predicted. Schools can use key stage 2 and 3* levelsAt key stage 2* and key stage 3* students are awarded National Curriculum levels to measure academic progressSchools are measured nationally according to attainment and progress. Progress is how well pupils have done given their starting points. For example, pupils' progress from key stage 2 to key stage 4 is measured.. The levels go from level 1 to level 8. In Year 9*, level 5 is the average nationally.* to measure how much value has been added. For example, a student with a level 5 at key stage 3* is normally predicted a grade ‘C’ at GCSEGCSEs, (General Certificate of Secondary Education) are the key qualification students take at key stage 4* when they are 16.They replaced ‘O’ Levels. Most schools make English, Maths and Science GCSEs obligatory. GCSEs have grades from A*–U. In the eyes of schools, colleges and the government, a ‘C’ grade is in effect a pass, a ‘D’ grade or below is a fail. Many further education* courses demand that students achieve five GCSEs at grades A*–C.*. If that student then goes on to get a ‘B’ at GCSEGCSEs, (General Certificate of Secondary Education) are the key qualification students take at key stage 4* when they are 16.They replaced ‘O’ Levels.

The teachers there put up with a much higher incidence of low level disruption. The student teacher deduced that this was because everybody had to try a lot less hard to get the results than in the undersubscribed school. In the undersubscribed school, the student teacher found that the students were expected to be more polite, and to work harder. Staff had more ideas and were less complacent. The student teacher decided to do her teaching practice in the undersubscribed school.
