"Stress is driving increasing numbers of teachers out of the profession, with some even considering suicide, a teaching union conference heard on Monday.

"[President] Piñera took office in March after two decades of centre-left rule. His centre-right alliance claims that despite a big rise since the mid-1990s in the proportion of young people at secondary school and university, standards have not improved. That is not borne out by the PISA results. Chile’s average scores have risen steadily since 2000."
