What might indicate the need for an adjustment in a vision training program?

The indication that an adjustment in a vision training program may be necessary is the lack of observable progress or the emergence of visual complaints. This suggests that the current program may not effectively address the individual’s needs or that the techniques being used are not having the desired impact on their visual skills. If a student is not showing progress despite consistent efforts in training, it warrants a re-evaluation of the program to identify potential barriers to learning, reasons for stagnation, or new strategies that might be more beneficial.

The other choices point to either positive outcomes or general attendance, which are indicators of engagement or success. Consistent improvement in reading scores reflects the effectiveness of the training, while regular attendance signifies commitment but doesn’t necessarily provide information about the effectiveness of the program. Constant praise from teachers and parents can affirm a student's progress but does not substitute for measurable visual skills improvement or address underlying issues that might require adjustment. Therefore, when progress stalls or new issues arise, that's a clear signal to reassess the vision training approach being applied.
