What does the acronym CUP stand for in the context of language acquisition?

The acronym CUP stands for Common Underlying Proficiency, which is a concept in bilingual education and language acquisition proposed by Jim Cummins. This theory posits that the skills and knowledge a learner develops in their first language can positively influence their proficiency in a second language. This underlying proficiency includes cognitive and academic skills that are transferable between languages, meaning that strong skills in the first language will aid in the development of similar skills in the second language.

CUP emphasizes the importance of developing students' first language skills, as this foundation supports their ability to navigate and acquire a second language effectively. This concept is particularly relevant for educators working with bilingual or multilingual students, as it highlights the interconnectedness of language skills across languages. By fostering Common Underlying Proficiency, educators can enhance students' overall language competence and academic success in both their native and second languages.
