The Academy is a 3x2 Room that allows you to train aka permanently buff your crew in it. These upgrades can boost your right side stats being Engine, Pilot, Repair, Science, and Weapon. Training can also be buffed with Education Researches to make them more effective. Thus, you should probably wait till your maxed out at level 11 to start mass training your more valuable crew. Since Common, Elite, and Unique Crew are easy to replace, there is no long term harm in spending excess minerals on their training early on.

What Is Training Capacity?
Crew have a built in limit on how buffed they can become. This limit is usually shown as a bar on the bottom of crew profiles. How close you are to this limit also affects your chance on what buffs you’re given and in what amounts. This is called Training Capacity:
To avoid back to back training, crew will sometimes get fatigued after they train. You automatically get Tier 1 Fatigue when you use a Yellow option, but you can also get tired from Green or Blue options if you back to back train your crew with them. When your crew gets fatigued, the amount of buffs they get from training is decreased. For Fatigue, you have to wait between 12 hours to 1 day for a Tier of Fatigue to be removed from them.
Tier 1 Fatigue, Small Training Penalty
Tier 2 Fatigue, Large Training Penalty
Tier 3 Fatigue, 100% Training Penalty
When you train crew, you get a variety of options to choose from. New Options also get added when you research Education in the Laboratory. Training also costs Minerals and gives some XP.

1 Buff = 1% Stat Bonus
When You Have Equipment along with Buffs, the formula becomes: Base Max Stat * (100%+Training Buff%) * (100%+Equipment Buff%). If a buff doesn’t increase the stat by %, just turn the * into a +.
