The effect of learning should be measured through observable performance outcomes. ACMP
highlights job performance as the most direct indicator, showing that knowledge and skills gained in
training are being applied. Communication (A) and teamwork (C) may improve indirectly, while stress
reduction (D) is harder to quantify. Tangible evidence comes when employees perform their roles
effectively in the new state, making job performance (B) the correct answer.
