Industrial-organizational (I-O) psychologists use psychology and statistics to solve people problems at work: who to hire, how to train them, how to measure performance, and how to make organizations healthier. This is a Job Zone 5 role, so most people hold a master's degree (58%) or a PhD (31%). You can start learning for free today, but a graduate degree is the real gateway to the title.

Stage 1 of 3 · about 16 weeks
Understand core psychology, basic statistics, and what I-O psychologists actually do, so you can prepare for graduate study.
Core psychology and research methods
Every I-O decision, such as choosing an interview format or a survey, rests on how people think and how we study them. If you know why a study design can mislead, you will not be fooled by vendor claims about 'science-backed' assessments.
Descriptive and inferential statistics
Nearly every core task, from evaluating program effectiveness to validating tests, is statistical. You need to read a correlation, a t-test and a confidence interval with ease before anything else.
Spreadsheet fluency (Excel and Google Sheets)
Excel and Sheets are on the O*NET software list because most early-career I-O work involves cleaning survey and HR data before any fancy analysis.
Learning what I-O psychology is
Knowing the field's map (selection, training, performance management, motivation, leadership, organizational development) helps you choose a graduate program that fits you.
