Parenting a high-potential athlete presents challenges, with key decisions having the power to impact a child’s sporting career. This study explores the decision-making process faced by tennis parents along the pathway, focusing on the factors influencing these choices within society. Using a longitudinal design, we tracked nine parents of high-potential Irish tennis players over 12 months, conducting interviews at three-month intervals. Through reflexive thematic analysis, we identified how decision-making evolves from generalised to highly individualised. The research also found that questionable information from stakeholders and personal/contextual factors heavily influence decisions. While informal reviews have proven helpful, there’s a clear need for a more structured framework. This study calls for increased attention to sport-parenting decision-making within society, proposing that educational support, combining specific information and reflective practice, can lead to better decisions. It also offers recommendations for sports governing bodies to better support parents, promoting a more informed and collaborative approach.
