As concerns deepen about the quality of education in Zimbabwe, parents can expect an indefinite extension of subsidising teacher salaries as the cash- strapped government struggles to meet the bloated civil service wage bill. Teacher incentives - a stipulated amount of usually between two to five dollars, which is paid by parents directly to teachers on a monthly basis - were introduced two years ago by the government to supplement teacher salaries. But many parents say the situation has become untenable and that they can no longer afford to contribute to teachers' salaries.
