Unlike free practice questions you'll find scattered online, our GSI prep tool gives you realistic test experience and actionable feedback. You'll go into test day already familiar with the format, the timing, and the scoring.
What is the GSI Exam?
The Guardian Selection Inventory (GSI) is a law enforcement entry exam that has replaced the older LST in many agencies. It measures cognitive skills, judgment, and behavioral attributes linked to officer success. The Guardian Selection Inventory (GSI) is the new standardized exam now used by many law enforcement agencies. It has replaced the older Law Enforcement Standardized Test (LST), bringing updated formats and scoring methods designed to better measure a candidate's readiness.
The exam evaluates areas like:
-
Cognitive skills (inductive & deductive reasoning, pattern recognition, selective attention, ordering, grammar, vocabulary, reading)
-
Situational Judgment (decision-making in law enforcement scenarios)
-
Personality & behavioral attributes (measuring traits tied to officer success)
Because the GSI is relatively new, many candidates aren't sure what to expect or how to prepare. That's where we come in.
How is the GSI different from the legacy LST?
The GSI uses updated question formats and scoring methods to better evaluate decision-making, personality traits, and readiness for law enforcement.
What sections are included in the GSI practice test?
Our practice exam covers all the major sections:
-
Cognitive Skills: Inductive & deductive reasoning, pattern recognition, selective attention, ordering, grammar, vocabular
-
Situational Judgment Test (SJT)
-
Personality, Style & Attitudes
-
Intercultural Sensitivity
How long will I have access to the practice test?
You’ll get unlimited access for 6 months from the date of purchase, so you can practice as often as you need.
How does the scoring work for the Personality, Intercultural Sensitivity and Situational Questions?
Our practice scoring is designed to measure commonly preferred traits and responses in law enforcement and to give you meaningful feedback on your strengths and areas for improvement. The precise algorithms and agency-specific thresholds used in the real exam are not publicly available and may vary by department. Use your practice exam results as a guide to preparation.
Do the practice tests show feedback?
Yes. After each test, you’ll receive a detailed results report with section scores, explanations, and personalized feedback so you know exactly where to improve. We'll also show you any responses that may trigger red flags and map to undesirable traits in law enforcement candidates.
Can I retake the practice exam more than once?
Absolutely. Each session pulls from a large bank of questions, so you won't get the same exact questions each time and can retake as many times as you want during your 6-month access period.
Will this guarantee I pass the real GSI Exam?
No. Every agency has its own scoring thresholds. Our tool is designed to help you prepare, reduce test-day anxiety, and improve your confidence—not to guarantee a passing score.
