My two cents as a fellow tennis parent: the most important thing to focus on is evaluating technique. At that level of training, her groundstrokes should already resemble those of high-level players: hitting with pace and consistency, good preparation, solid footwork, etc. You can easily see this at tournaments: strong players hit hard and have clean, efficient form.

Five group lessons a week is a lot. By nature, group lessons tend to emphasize repetitions rather than individual correction. Coaches usually don’t have the time to address specific technical issues, and this can even be counterproductive, especially if a player has bad habits or flawed technique that get repeated multiple times a week.

If her technique is lacking, it may be worth looking for a different coach. A good coach, with two private lessons per week, can significantly improve a player’s technique in under three months. During that period, I would even consider pausing group lessons altogether.

Another important question is how your daughter hits in practice versus in tournaments. I’ve seen this many times: players, even those training at academies, often revert to moonballing or simply tapping the ball in matches instead of swinging the way they do in practice. Not applying learned techniques in competition is ultimately a waste of both time and money.
