At the end of the 2009-2010 school year, Cassidy was awarded her varsity letter and received a plague for her performance in track & field as most improved during her Freshman year.

She spent the year learning how to do the "four step" in the 100 meter hurtles and learning how to make it over hurtles that were 3 inches taller than in Junior High.

She also participated in the 300 meter hurtles. This was her first year doing it and is a killer race. By the end of the year she was running in the 51.3 second range. At the first of the year she was running 55-56 seconds. She also became the top 300 meter hurtle runner at the high school beating out the others one of which was a junior.
