Twenty-five years ago, the author contributed a historical review of evidence on the foreign language (FL) learning problems of low-achieving and learning disabled (LD) students. Educators had proposed a new disability, FL learning disability, and developed policies permitting LD students to substitute courses or waive the FL requirement. The introduction of this new disability was premature because empirical evidence found no relationship between FL learning problems and LDs. Even so, several misguided assumptions about a unique disability for FL learning and a special relationship between FL learning problems and LDs persisted, and an LD diagnosis became the de facto criterion for FL course substitution/waiver policies. In this updated review, these assumptions and evidence falsifying them are examined. Cultural reasons for the assumptions about FL learning and LDs and the adoption of course substitution policies are proposed. The author concludes with recommendations for policymakers.
