Nikki earned her BA in Psychology and Cognitive Science from the University of Virginia. She has been using the CLASS tool since 2010, when she worked as a Pre-K CLASS coder and research assistant at the Center for the Advanced Study of Teaching and Learning. She is now the Observer Support Manager at Teachstone and loves being able to support others in conducting classroom observations with fidelity. Her expertise is in live and videotaped CLASS coding, and she is certified on all age levels of the CLASS tool, Infant through Secondary. In her free time, Nikki likes going to the movies and wine tasting with her friends and family. She also enjoys yoga, puzzles, and playing with her Cavalier King Charles Spaniel, Neo.
