Robert Mugabe, Zimbabwe's president, was once hailed as the man who made his country's education system a success.

In spite of political and economic problems in the country, Zimbabwe has one of the highest literacy rates in Africa and once boasted some of the finest public schools on the continent.

But Zimbabwe's education system is now in crisis and its poorly paid teachers are leaving government-run schools in the thousands.

As Al Jazeera's Haru Mutasa reports, many parents are now searching for alternative resources to educate their children.
