Why choose the Integrated Curriculum Model (ICM) in an effort to "raise the bar" for all students? Results of an intervention targeting kindergarten through grade five students in Title I schools using the ICM to change teacher perceptions of student abilities are reported. We describe the ICM as a component of school-wide intervention and connect to research on teacher beliefs about student abilities and instructional practices. This study includes explication of the ICM and other components in a Javits-funded intervention to change teacher perceptions and beliefs about talent in low-income learners. Teachers observed more high potential in students after 2 years' intervention. Teacher engagement with professional learning correlated with change in beliefs and practices. Teacher beliefs changed when they saw and understood high-level curricula and instruction through examples grounded in the ICM and linked to the psychology of learning.
