"Inclusion" is hard to implement worldwide. In the U.S.A. and Canada, one obstacle is the division between "general" and "special" education. To facilitate inclusion of exceptional students, a new model of teacher training is needed. This piece introduces the System for Understanding Individual Learning Performance (S.U.I.L.P.). Derived from neuropsychology, cross-cultural psychology, education, and sociology, the S.U.I.L.P. provides a holistic framework and common vocabulary for understanding learning performance in all learners--across development and different contexts. It also establishes avenues for collaboration and eventual merging of general and special education.
