Parents pay $75k for Alpha's AI school. Half of its students missed math target

Alpha School, a network of AI-driven private schools charging parents up to $75,000 annually, has gained backing from Silicon Valley and the Trump administration despite internal data showing that only 42% of its students met the goal of learning twice as fast in both math and reading. The school replaces traditional teachers with "guides" and relies on an AI tutoring app called TimeBack to compress academics into two hours daily, but the disappointing results raise questions about its central promise as it expands into public school systems.
