About Us


NCSS was founded in 1981 to supply statistical software to the research community. Since then, tens of thousands of customers have used NCSS software (NCSS and PASS) for statistical, graphics, and power analysis / sample size purposes. The company is led by Dr. Jerry Hintze, an experienced Ph.D. statistician.

Our Mission

For the last 36 years, our mission has been to provide accurate, user-friendly, fully-supported statistical analysis, graphics, and sample size tools. We seek to produce applications the research community requests, as well as new tools to guide improvement in analysis and sample size estimation.

"PASS is a great program. It does so much and is easy to use. It’s much better than the other sample size programs I’ve used—it has helped me greatly in my research."

Ken Lawson, Ph.D., The University of Texas

"I purchased NCSS last week and have been extremely impressed with the product so far. The documentation is superb... Especially strong is the importing of files from Excel and other statistics programs..."
