This systematic review summarizes and categorizes studies between the years 1990 and 2019 that investigated differences in sport-specific technical skills in young athletes from different skill or performance levels and/or the role of these skills in predicting later performance.

The included studies highlight the value of sport-specific technical skills in TID for discriminating different skill or performance levels and/or predicting later performance while depicting the narrow and limited knowledge we currently have in regard to different populations and various assessment methods.

These findings can be used by scientists to develop innovative study designs potentially providing new insights into TID, as well as by administrators and coaches to improve selection procedures and decision-making in TID contexts.
