1. No, the unique individual student of a UC college/university is not becoming less literate by the day. They're actually becoming MORE literate while enrolled.
2. Yes, the colleges and universities acknowledge that graduating 12th-graders are significantly less capable in math and reading than 10 years ago and are still admitting them to their freshman classes. Thus, the overall competencies of the enrolled student populations are lower than in the past.
Why is this happening?
1. Long-term strategic degradation of public education
-- Massive coordinated defunding of public education over the last 30 years (private school vouchers, funding reductions).
-- Coordinated invasion of the education management sphere by people with no educational background for the purpose of pushing political/social agendas.
-- Over-empowering parents to influence or pressure educators to give certain grades.
2. Continued devaluing/undervaluing of the teaching profession
3. Some **horribly misguided universities** prohibited the use of standardized tests in admissions (some temporarily, some ongoing). This allows students hyper-inflated high school grades and easily-cheated essays to be able to enter university without proving their competencies.
4. Massive defunding of colleges and universities via changes to research funding and direct funding force those campuses to accept less capable students to just keep the lights on.
So ya... this isn't new. It's not sudden. It doesn't come as a surprise. Anyone who's been embedded in higher education for the last decade or more has seen it all coming. And the faculty are so sick and tired of basically having to teach remedial high school courses to people who are supposed to be in the top 10% of students are starting to rebel.
