We sponsor and host a number competitions but the main one is the Mercer Science and Engineering Fair (MSEF). This fair DOES NOT support team projects. Senior division team projects may participate in nearby ISEF affiliated fairs. Check out the details for our other competitions, many of which do allow team projects.
Please contact the MSEF fair director who will contact the other fair so you may compete in that fair.
Note that other ISEF-affiliated fairs have different registration dates and requirements. Also, you may only compete in one ISEF-affiliated fair per year. It is recommended that you register as early as possible.
