Training Support Center (TSC) Great Lakes is one of Naval Station, Great Lakes largest tenant commands, supporting technical post-recruit training and other training in a number of disciplines, in about 80 different courses of instruction. The five Learning Sites and one unit supported by TSC provide approximately 85 percent of the Navy's initial surface warfare training. The Great Lakes Learning Sites make up the Navy's largest technical training operation, with an annual throughput of approximately 13,500 students and up to 5,000 students on board at any time. Many of the courses offered at the Great Lakes Learning Sites and one unit are also attended by several International Military Students each year.

Training Support Center provides military leadership, Navy/Military Training, student control, berthing, and other support for students attending courses at the following Learning Sites and one unit.

There are five learning sites located at TSC:

- Center for Surface Combat Systems (CSCS)
- Center for Naval Engineering (CNE)
- Center for EOD and Dive (CNEODD)
- Center for Personal and Professional Development (CPPD)
- Center for SEAL and SWCC

Most of the courses offered at the Great Lakes Learning Sites have been granted education credit by the American Council on Education. The learning sites participate, with the centers they report to, in a quality-assurance accreditation process sponsored by the Commission of the Council on Occupational Education.

To ensure the command continues to send quality Sailors to the fleet, training is balanced between the technical aspects of the rating, along with reinforcing and continuing the military training initiated at Recruit Training Command (RTC). Every student is provided with a solid base of training, both military and technical, before departing Great Lakes to continue his or her career in the fleet.
