You are missing the key ingredients for having the right to make this or any related claim, such as:
- What level were those students achieving at before they started Program X?
- What was their growth in learning (choose whatever content area or 21C skill you want) during their involvement in Program X?
- If they left Program X, was their learning growth sustained or not?
- Was the learning growth consistent across ethnographic differences in the group of students (if indeed there were any)?
- Was there a control group of non-Program X students with similar characteristics and how did they perform (before, during and after the study)?
The number of claims made for this or that and their impact on learning gets a little tiring because most are based on shoddy studies, subjective observation or just plain wishful thinking.
Educators should do better than this.
