## What is SFST Guide and Grade?

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.
