Officer Candidates who attend the Platoon Leaders Class may opt for either the PLC Juniors/Seniors program or the PLC Combined program. In the Juniors/Seniors program, a freshman may attend the PLC Juniors course the summer between their freshman and sophomore years, then attend the PLC Seniors course the summer before their senior year begins. Sophomores can attend the PLC Juniors course the summer before their junior year in school and the PLC Seniors course the following summer. PLC Combined is a ten-week program for those interested in completing officer screening during a single summer after completing their junior year in college.
