The term "MEA" can refer to different things depending on the context. Here are some possible meanings:

• Michigan Education Association: This is a self-governing education association that represents about 120,000 teachers, education support professionals, and higher-education employees throughout the state of Michigan. Its mission is to protect, advocate, and advance the rights of all education professionals to promote quality public education for all students.

• MEA conference: This is an annual professional development event for educators in Minnesota that takes place on the third Thursday of October. It is hosted by Education Minnesota, a union of educators that represents around 86,000 educators who work in the states pre-K-12 and post-secondary academic settings. The conference is free for Education Minnesota members and aspiring educators, but registration is required.

• MEA weekend: This is a break that Minnesota teachers and families look forward to every year. It usually coincides with the MEA conference, but they are not the same thing. MEA originally stood for the Minnesota Educators Association, which was one of the unions in the state. In 1998, it merged with another union, MFT, to form Education Minnesota. MEA weekend became the "Minnesota Educator Academy" to keep the acronym consistent. Teachers are not required to attend the conference, nor do they get paid to. Member dues cover costs.

• Minimum En-route Altitude: This is the lowest altitude to be flown in an airspace structure that assures reception of navigation aids necessary to navigate accurately along the required route, two-way communication with air traffic control, safe clearance from obstacles within the sector, and compliance with the airspace structure. It is abbreviated as MEA.

• Other meanings: MEA can also be an acronym for other things, such as "Middle East Airlines," "monoethanolamine," or "Minnesota Electrical Association".
