Center for Applied Linguistics

What Center for Applied Linguistics does

The Center for Applied Linguistics (CAL) is a Washington, D.C.-based nonprofit research and professional development organization founded in 1959 by linguist Charles A. Ferguson. It operates across seven stated areas of impact: Adult Literacy and Language Education, Dual Language and Multilingual Education, Immigrants and Newcomers, International Language Education, PreK-12 EL Education, Testing and Assessment, and World Languages. Its primary constituents are K-12 educators and administrators serving English learners and multilingual students, state education agencies, and the WIDA Consortium, with secondary audiences including dual language programs, heritage language communities, and immigrant/newcomer service providers.

CAL's core product and service portfolio comprises three main delivery mechanisms: (1) CAL Solutions (solutions.cal.org) for fee-based professional development institutes including the CAL Literacy Institute, Spanish-English Biliteracy Instruction Institute, Leading Dual Language Programs, and a family of SIOP (Sheltered Instruction Observation Protocol) training programs; (2) the CAL Store (calstore.cal.org), an e-commerce channel for publications, practitioner briefs, and educational materials; and (3) assessment and consulting services, including Standards Expert review work for the WIDA ACCESS test and technical assistance to school districts and state education agencies. Supporting the commercial portfolio is a substantial content archive — 100+ CAL Digests, Heritage Voices profiles across 18 languages, Heritage Briefs, the CAL Commentary series, and the digitized Linguistic Reporter newsletter (1959-1982) — alongside a free Resource Center offering webinars, online learning modules, and the free Student Oral Proficiency Assessment (SOPA) Training Program developed with U.S. Department of Education funding.

Revenue derives from four streams: fee-based professional development institutes and workshops, publications and product sales through the CAL Store, government and foundation grants (notably from the U.S. Department of Education), and consulting/technical assistance to districts, state agencies, and international organizations. Distribution is multi-channel: direct enterprise sales through CAL Solutions and on-site district engagements, e-commerce through the CAL Store, and free top-of-funnel content marketing via the cal.org website, social media, webinars, and conference presentations at TESOL, AAAS, AERA, and WIDA. CAL is led by President & CEO Diep Nguyen, Ph.D. (appointed 2024) and governed by an independent Board of Trustees, with no parent company, external investors, or M&A activity indicated.

Direct peers

• WIDA Consortium: University of Wisconsin-Madison housed consortium developing English language proficiency standards and assessments for K-12 ELs across 40+ member states. Directly comparable as the assessment framework CAL supports, serving the same K-12 EL educator and state agency customer base.
• TESOL International Association: Global professional association for English language teaching professionals, providing publications, certifications, and conventions. Directly comparable to CAL's professional development and thought leadership mission for EL educators, with overlapping conference and publication channels.
• National Association for Bilingual Education (NABE): National membership association advocating for bilingual education and serving educators of English learners. Directly comparable mission and customer base to CAL's dual language and bilingual education programs.
• American Council on the Teaching of Foreign Languages (ACTFL): National association supporting world language educators with proficiency standards, assessments, and PD. Comparable to CAL's world languages and dual language work, including overlap in assessment development and teacher certification.
• National Heritage Language Resource Center (NHLRC): UCLA-based federally-funded center focused on heritage language research and resources. Direct peer to CAL's Heritage Voices and Heritage Briefs programs, serving overlapping community-based heritage language schools and researchers.

Emerging players

• SEAL (Sobrato Early Academic Language): California-based nonprofit providing EL/DL professional development, coaching, and curriculum to school districts. Comparable emerging competitor in the same dual language and English learner PD market as CAL's institutes.
• Laureate Learning Systems: Provider of language learning and assessment products for English learners with disabilities. Comparable niche player serving overlapping EL student populations, particularly in special education.

Broad incumbents

• American Institutes for Research (AIR): Large nonprofit research organization conducting education policy and assessment work for federal and state clients. Comparable in education assessment and research, but operates across all subjects rather than specializing in language like CAL.
• Council of Chief State School Officers (CCSSO): National association of state education agency heads that hosts WIDA and influences EL assessment policy. Comparable as a convening/influence body for state-level EL education decisions, though broader in scope than CAL.
• Educational Testing Service (ETS): Large-scale educational assessment organization producing tests including TOEFL and Praxis. Comparable in language assessment development expertise, though operates at much larger commercial scale than CAL's assessment work.
