Since 1994, the National Science & Maths Quiz (NSMQ) has been a significant educational competition put on by Primetime to help schools exhibit their competence in Science and Maths through representatives selected by the school authorities.
Old students and continuing students in the nation have a lot of fun watching the NSMQ competition. The NSMQ is one of the most talked-about events in Ghana.
Ever since the competition first began, it has been held each year with the exception of 2010 and 2011.
During this event, Senior High Schools gather during prelims to compete against each other for quarter-finals to eventually get seeded and hopefully win at the finals. All seeded schools are exempted from preliminary stages the following year.
This article provides a full list of past winners of NSMQ Ghana. As of 2022, only 10 schools have won the final trophy. These schools are listed here: Full List Of Schools That Have Won NSMQ Since 1994.
