Schooling or fish schooling describes a phenomenon where the mistakes of loose-passive players weigh less heavily on their equity because there are many of them. The individuals who make bad, unprofitable calls are aided by the fact that others doing the same thing increases everybody's pot odds.

Example (Texas Hold'em):

Player A Player B Player C Board
The pot is $4. Player C bets $3. Players A and B, who are loose, call. They have inside straight draws with 4 outs, meaning they cannot call profitably. They are making a mistake because the cost of the move is too high. But if one differentiates between two cases, one where only A and C are involved and one where B is also involved, then the following holds:

In the first case, A calls $3 in a seven dollar pot. His pot odds are 7:3. In the second case, though, B also adds $3 to the pot, increasing A's odds to 10:3. The presence of another loose, weak player has lessened the effect of both of their mistakes.

Schooling is a reason why weak, loose players can hold their own in weak, loose games. They call too much with marginal hands, but the other players do it too and everybody comes out ok.
