Rankings don't tell whole story - but Ireland's slide down chart can't be ignored
I've spent most of my career in education flagging the limitations of different forms of measurement.
Standardised tests of the reading and mathematics achievement of children in primary schools are only a moment-in-time measure. Written tests and examinations in post-primary schools can only measure a limited range of skills. Add high stakes to any test, and they can influence the educational experience the test is supposed to measure.
Today, I find myself adding a new limited measure to my list - university rankings.
