Disagree with post #6 about “not interfering with family values”. It all depends what those are. Some ideas need to be challenged and ways questioned.
US HS education is a continuation of critical thinking, skills mastery and knowledge foundation building. It also includes learning to deal with peers- social skills, gradual taking charge of one’s life and other transitions to adulthood. Our current day society has the luxury of letting teens attend school instead of needing to work like my grandfather did after 8th grade. Likewise college is available to many more than in my parents, and even my, generation.
I like that every student can get the same diploma- despite some areas choosing different wording it is still a statement of being a HS grad.
