(Corbin & Strauss, 2008), data were analyzed through a process of open coding, axial coding, and theoretical integration. The resulting grounded theory highlights the need to provide tennis parents with education that covers their introductory needs, organizational needs, development needs, and competition needs during childhood/mini tennis (5-10 years) and early adolescence/junior tennis (11-14 years). The theory is based on the notion that these needs can only be fulfilled if tennis parents are provided with formal education, and that the effectiveness of this education will be determined by parents' motivation to learn and the on-going support they receive from key stakeholders (e.g., coaches). The content, structure, and timing of parent education and support in high performance tennis centers are discussed. theory highlights the need to provide tennis parents with education that covers their introductory 7 needs, organizational needs, development needs, and competition needs during childhood/mini tennis 8 (5-10 years) and early adolescence/junior tennis (11-14 years).
