Training Corps

The 104th Trainees Squad is the only graduating class introduced in the series and contains nearly all of the central characters.

The top ten of the class, those with the best grades, included, in order: Mikasa Ackerman, Reiner Braun, Bertolt Hoover, Annie Leonhart, Eren Yeager, Jean Kirstein, Marco Bott, Connie Springer, Sasha Blouse and Krista Lenz. As with all graduating classes, only those in top ten can apply to the Military Police, giving them the privilege of living in the Inner District. The 104th was disbanded at the end of the graduation ceremony.

Another one also not in the top ten, but is considered in it is Ymir. Her abilities are rumoured to easily surpass Krista Lenz's but because of unknown reasons she left the spot to her.

Interestingly enough, the top five graduates (excluding Mikasa Ackerman) are known Titan shifters. And of all top ten graduates, only Annie Leonhart applied to the Military Police; Marco Bodt died and the other 8 joined the Survey Corps.

The anime states that there are 218 graduates of the 104th Trainees Squad.

Instructor Shadis' Individual Trainee Evaluations
104ème Brigade d'Entraînement
 * Reiner Braun - "A strong soldier, physically and mentally. Excels at teamwork and is trusted by all of his comrades."
 * Armin Arlert - "While lacking in physical strength, he's demonstrated an extraordinary aptitude for his studies."
 * Annie Leonhart - "Her strike form is flawless, but she works poorly with others and tends to isolate herself."
 * Bertolt Hoover - "He has great potential, but lacks initiative."
 * Jean Kirstein - "A master of 3D Maneuvering Gear, his brash personality often causes friction with the team."
 * Sasha Blouse - "She has unconventional, good instincts, but they make her unsuited for teamwork."
 * Connie Springer - "He demonstrates superior physical agility, but lacks mental acuity."
 * Mikasa Ackerman - "A master in all areas. Her talent is unprecedented and she is considered one of the best trainees in our history."
 * Eren Yeager - "While not currently exceptional in a given area, his iron will has improved him drastically, and he possesses the greatest motivation out of all the trainees."
