Let districts decide and allow parents the option of opting their students out of the requirement if the school or district creates it as a graduation requirement. To expect every student to do a massive senior project is unreasonable. Colleges want more information than just GPA and SAT score. They want to know what the student has done and can do. Senior project is too easy.
Senior project is too hard.
Senior project is too time-consuming. Every student can achieve to some level and deserves appropriate recognition. One diploma with earned endorsements. We cannot legislate world class performance. Issue a diploma with scores, period.
