What can I expect from the application and testing process when applying for positions through the National Testing Network?

When applying for public safety positions through the National Testing Network (NTN), candidates typically schedule exams at authorized testing centers or complete online assessments depending on the agency's preferences. The process often includes written tests, video-based situational assessments, and sometimes physical ability evaluations, all designed to simulate real job scenarios. Candidates should be prepared for a structured and standardized process that emphasizes fairness and consistency across departments. It's also common to receive detailed instructions and access to preparation materials prior to testing, helping applicants feel confident and informed throughout the process.

What is the National Testing Network?

The National Testing Network (NTN) is a service that provides testing and assessment solutions for public safety departments, including law enforcement, fire, emergency communications, and corrections agencies. It allows candidates to take standardized exams for multiple agencies at authorized testing centers across the United States. NTN streamlines the hiring process by offering consistent, validated testing and making it easier for candidates to apply to multiple agencies at once. This helps agencies efficiently identify qualified applicants and fill open positions more effectively.
