Hi Marisol, and thanks for contacting CTB. I was away from my office for several days so have not beenn able to respond until now.
Attempting to achieve a transportation policy change probably will be difficult unless several families in your immediate neighborhood also join you in requesting either a change in policy or an exception to policy; or unless your child(ren) qualifies for reasonable accommodation because of a handicap. So I suggest first that you canvas your neighbors to see who might be willing to join in submitting a request, and make certain that all of you have consensus about a reasonable solution. You might ask everyone to sign a letter of request. Then ask for a meeting with the school district''s transportation director to make certain the problem and need are understood, and to work together to find a solution that the transportation director can support.
Note that I have checked several "competencies" that may or may not help your planning. Your issue is pretty straightforward and the above process represents a good approach. I hope this is helpful.
