TOPS is a talent identification program whose goal is to identify young girls who may have talent for the elite path. TOPS training generally consists of mostly strength and flexibility, but there are some skills as well. Generally, girls age 7-10 who do TOPS test in the summer and then can qualify to national testing. The highest scoring girls from that make the TOPS national team, and get to train at the ranch during TOPS camp(well, not anymore).
Having said that, some elite gyms choose not to participate in TOPS and it certainly isn’t necessary.
