JASI was formed in 1971 to meet the professional development needs of law enforcement and public safety professionals. Since then, hundreds of municipal, county, state, and federal police agencies have entrusted JASI to train thousands of law enforcement professionals.

Today, under the leadership of director Steve Shelow, the JASI training portfolio also includes the Pennsylvania Child Support Enforcement Training Institute (PACSETI) and the Pennsylvania Sheriff and Deputy Sheriff Training Program.

JASI partners with Penn State Harrisburg and the Penn State Justice Center for Research to provide justice-related training, education, and organizational development to government agencies, private firms, and communities.
