Job outlook & demand
The BLS projects I-O psychology to grow as organizations invest in hiring, retention, training, and morale. It's a small field, so roles are competitive, but demand from tech, consulting, and large employers is strong.
Pay: median, range & trajectory
I-O is the highest-paid psychology specialty. The BLS median has been reported as high as $193,950 (May 2025) — but treat that with care: the survey counts fewer than 1,000 salaried jobs, so the figure swings sharply year to year (it was ~$147,420 in 2023 and ~$109,840 in 2024). Even at the conservative end, I-O pay is among the strongest in psychology.
