Mongolia has experienced a remarkable period of heavy investment in skills development related education and training to meet the rapidly growing demand for skilled workers and technicians in the key economic sectors of construction, the extractive industries and civil engineering. The demand has exceeded supply so the government, donors and the private sector have invested an unprecedented volume of time, energy and money to stimulate new regimes of industry-led education and training. This remarkable period of spending on the education-economic development nexus over 2008-2013 began to decline in 2014. Now a more modest period of spending coupled with robust sector planning has commenced. During this period of both rapid growth, and an equally rapid decline, secondary school and post-secondary school teacher training and re-training have been relatively neglected. This is odd, as it is generally understood that the difference between an over performing education sector and an underperforming one, is the quality of teachers, the quality of teacher training and the overall national effort in the quality improvement of teachers and teaching.
