leftBrain Performance GritABC™ is a performance intelligence platform.

We assess, quantify and track the mindset performance skills that drive execution and turn those skills into something measurable and trainable.

We bring clarity to the conversation around intangible skills

You can’t improve what you don’t measure. We’ve built a system that measures mindset performance, guides development and proves improvement.

Our scientifically-proven assessment measures the dimensions Attitude, Behavior & Character. Each report provides an inventory of skills that highlight strengths and areas for improvement.

Why GritABC™ skills matter:

Understanding and improving attitude, behavior, and character helps individuals optimize performance, build resilience, and create long term success. There are five core aspects of these intangibles that help predict performance.

The GritABC™ Skills assessment has 195 sliding scale questions and takes 20-30 minutes to complete. Your results will help you understand yourself better, how you can grow as an athlete, and how to communicate better with your coaches.
