This is obviously caused by even more DEI, or AI, or EMI, or perhaps the FBI. Either way it's a liberal plot to dumb down the population so they can take control.
But don't worry, Trump's on it. He's kicking the DEI out of education, helping billionaire tech bros kick the liberal bias out of AI, banning wind turbines and defunding solar panels and EVs which emit brain-destroying electromagnetic waves, and repurposing the FBI to sanitize the Epstein files neutralize the real enemies of the State - liberals.
By this time next year you can bet those math and reading scores will be through the roof!
