Key findings include a "bilingual paradox" where students taking the STAAR in Spanish sometimes outperform English test-takers, as seen at Cromack - Castaneda Elementary where 4th grade Spanish reading proficiency hit 66.67% versus 49.07% in English. The two Idea schools consistently underperform the district average despite lower poverty rates and spending. Science remains a universal weakness, with most schools scoring below the state average in 5th grade science. Notably, high poverty does not prevent success, as top schools like Ortiz (94.33% free/reduced lunch) and Burns (93.7%) demonstrate that strong leadership and effective teaching can overcome socioeconomic barriers.
