In primary education, for the same school year, about 25% of teachers did not have a higher education degree (NCESE, 2013a). As a comparison, the average proportion of teachers with no higher education qualification in education systems participating in the 2013 cycle of the OECD’s Teaching and Learning International Survey (TALIS) was 2.3% (OECD, 2014c). This might reflect some ageing of the teaching profession. However, the teaching workforce remains younger than the average in the OECD area.
