Not remotely above average for people with a postgraduate qualification
Also from your link/s:
We classify a PhD as a higher qualification than masters and PGCEs, and masters as higher qualifications than PGCEs
Arts and humanities students are less likely than STEM students to study for a masters or PhD, but are much more likely to to a PGCE.
We see that returns to doing a PGCE are lowest for those with the best outside options: those studying at the highest-status institutions or having studied undergraduate degrees that on average lead to high earnings.
Median earnings of PGCE graduates are higher than those of undergraduates and nearly as high as those of masters graduates.
In general, we show that postgraduate degrees appear to offer insurance against bad labour market outcomes. This is particularly true for PGCE qualifications, which significantly increase the chances of having ‘good’ earnings by age 35, but simultaneously reduce the chances of achieving moderately high earnings (for example, above £50,000).
primarily due to PGCE students having studied undergraduate subjects with lower earnings potential on average. We get a final estimate of the returns to PGCEs at age 35 of -2% for men and +1% for women.
