Who we are

Launched in 2014, Diglossia is a global language company dedicated to changing lives by fostering language development and literacy throughout the world.

Diglossia's suite of language assessments provide valid and reliable data to make informed decisions when evaluating language program effectiveness, adopting new curricula, and targeting professional development needs.

Using innovative research and technology, our K-16 assessments address the unique needs of the fast-moving language education landscape. We partner with leading scholars and institutions to serve language learners around the world.

Diglossia was founded with a dedication to promoting Arabic literacy in the MENA region. In an effort to address the need for standards-based Arabic literacy assessments, we are honored to partner with The Arab Thought Foundation and the Aribi21 Project in the development of Mubakkir, the first online test to measure literacy development in Arabic early language learners. The test is based on the Arabic Reading Level Standards developed by Dr. Hanada Taha of Zayed University and can be used by both native and non-native speakers.

We also offer TALA, the first Arabic Language Arts assessment designed for native speakers. TALA tests vocabulary, reading and writing against the World Language Initiative Arabic standards. Other offerings include Lexica vocabulary and placement assessments for both English and Arabic speakers.

Our Professional Development workshops offer onsite, online, or blended solutions to help teachers and administrators stay on the cutting edge of best practices in language assessment. In addition to serving the education sector, Diglossia works with employers and industries to provide custom workforce screening and language proficiency tests in both English and Arabic.
