About PST

Public Safety Testing was formed in 2000 to assist local governments ease the burdensome process of establishing and maintaining eligibility lists for positions such as firefighter, police officer, deputy sheriff, corrections officer, 9-1-1 dispatcher and others. We conduct advertising and professional recruiting assistance, application intake processing, written testing and physical ability testing for those agencies that subscribe to our service.  Currently more than 200 police, sheriff, fire, and dispatch agencies in the Pacific Northwest contract with our firm for their initial pre-employment testing services.  We have had the privilege of helping hundreds of agencies hire thousands of police officers, firefighters, corrections officers and 911 dispatchers

Subscribing agencies have consistently indicated that by utilizing our services they are saving money, saving staff time, and the quality and diversity of applicants has been enhanced.  Agency representatives appreciate that the applicant pool is limited to candidates that have passed the written and physical ability exams and want to work for their agency.  Continuous testing ensures that eligibility lists are frequently updated with new candidates so your list is always up to date.  This is critical in today’s competitive hiring environment.

We engage in a vigorous marketing and outreach strategy focused on attracting high quality and diverse candidates.  Our efforts target a broad range of communication mediums including on the internet, career fairs, military, recruiting posters, colleges, newspapers and a close-working relationship with our client agencies.

We conduct tests frequently in the Pacific Northwest offering testing in communities where our client agencies are located and where they typically draw their candidate pool.  Each year we offer hundreds of opportunities for candidates to take their exams throughout the Pacific Northwest.  In addition, through a partnership network of college testing facilities, we also have the ability to offer your applicants written testing in all 50 states.   

Applicants are very attracted to the PST system because they are able to test for any agency that we represent anywhere and anytime we are testing.  Applicants register online, choose the testing date/location most convenient for them, participate in one written and one physical ability test and have their scores sent to one or more agencies of their choice.  Applicants (and agencies) receive their written and physical ability scores on the day that they test.  This one-stop-shop concept has served applicants and subscribing agencies well since 2000.

There are many robust features of our website for agency representatives.  You can access your pre-tested applicant pool 24/7 via our secured website; view candidate data and test scores, and view and download a comprehensive 28-page Personal History Statement for each of your candidates.  In addition, a detailed Candidate Test Performance Report is provided for each candidate showing how they performed on every dimension and sub-dimension of the written examination.

We have a demonstrated track record and a proven system which simplifies your hiring process, enhances the quality of your candidate pool, and saves your agency significant staff time and money.
