While the nation's bilingual classrooms are bustling with a diverse and growing population—now nearly five million strong and increasingly served by inclusive dual-language models—the sobering reality is that these programs are still a patchwork quilt, brilliantly effective where they exist but often failing to reach every student in need, especially as they climb the grade ladder.
