From the Bahamas Chamber of Commerce report on education:

The BGCSE Report [2004] states “Were it not for the Private schools and a few public High schools in the Family Islands, the Mean Grade for the country would have been an astounding E [rather than D]. This [level of academic achievement] is totally unacceptable.” The Mean Grade for the Public High Schools on New Providence was F+ while the Mean Grade for the Private High Schools on New Providence was D+. Both the absolute levels and the gap between the two are truly disturbing.
