The most effective way to evaluate whether adding a ramp in front of a school solves a problem is: by determining whether the ramp allows students using wheelchairs, braces, and crutches to enter the school more easily. This is because it helps answer the question: Is it worth it? For instance, if there is only one step in the school entrance, then a ramp would be more trouble and a person in crutches would probably prefer avoiding the ramp. Before analyzing whether the ramp complies with the laws or if more ramps would need to be built, it is important to know if the ramp is worth it in the first place. Finally, influencing other schools would be a side effect but that wouldn't solve a problem.
