 Some schools will insist that the student only 'team-teach' with the qualified teacher present at all times until it is felt the student can cope on his or her own.GTP students are allowed to train on a more limited age range than the PGCE.At secondary level an example would be to train in two Key Stages, such as Key Stage 3 (Years 7-9 ages 11–14) and Key Stage 4 (Years 10-11, ages 14–16), rather than the full age range of 11-18.
