SFST Guide and Grade

Conduct SFSTs with confidence. SFST Guide & Grade puts HGN, Walk & Turn, and One-Leg Stand guidance, clue tracking, scoring, and evaluation tools in one field-ready app.

SFST GUIDE & GRADE A field-ready reference and evaluation tool for law enforcement officers conducting or studying Standardized Field Sobriety Testing (SFST). SFST Guide & Grade brings the three standardized field sobriety tests together in one streamlined workflow, helping officers quickly reference procedures, record observed clues, and keep track of scores. FIELD-READY SFST WORKFLOW Move through an evaluation from HGN to Walk & Turn to One-Leg Stand without losing your place. Keep your observations organized and your scoring calculated as you work. HGN Reference HGN procedures and record applicable clues with automatic clue counting. WALK & TURN Follow the procedure, record observed clues, and let the app keep track of the score. ONE-LEG STAND Record observations and automatically calculate the applicable clue count. QUICK REFERENCE Keep SFST procedures and reference information readily available when you need a refresher. EVALUATION TOOLS Organize an SFST evaluation in one place with session-based scoring, observations, notes, and a final summary. BUILT FOR THE FIELD Designed around a simple, fast interface that minimizes unnecessary taps and keeps important information easy to find. Dark-friendly styling and large, clear controls make the app practical for use in a variety of environments. SFST Guide & Grade is designed as a professional reference and documentation aid. It does not make legal determinations or independently determine impairment. Important: Always follow your agency's policies, applicable law, and current SFST training and instructional materials.
