An alternative to the graduation test requirements

A coalition has outlined an alternative to the graduation competency test requirements that call for students to pass tests in a number of subject areas to graduate.
The Coalition for Effective and Responsible Testing said a valid assessment should not depend on a single test score and that a student who fails its tests would not necessarily be prevented from getting a diploma.
The coalition said their voluntary tests could eventually supplant the 11th grade Pennsylvania System of School Assessment tests to show the yearly progress that is required by federal regulations.
What do you think should happen? Should Pennsylvania students have to pas tests to graduate?
