Language Learning for Military
Personnel & Their Families

Transparent Language Online and the CL-150 Platform (also known as the CL-150) are very different programs in what they offer and the communities they serve. However, when used together, these two programs serve all of the varied language-learning needs of the wider military community.

Military-Specific Learning

Military-Specific Learning

Sponsored for US Government employees and military personnel and programs by the DOD's web portal, Joint Language University (JLU), the CL-150 is for military professional training. The CL-150 offers a broad selection of language-learning materials aligned to various Government schools, language programs, and language curricula. The CL-150 also includes authoring capabilities and an instructor portal with class management.

Military-Specific Learning

Personal Enrichment and
Recreational Learning

Available to all Navy Library customers

Transparent Language Online is designed for personal improvement. Sponsored for all Navy library customers by the Navy Library library program, Transparent Language Online is available to all library customers, including spouses, families, and the base community. The program offers a similar broad array of languages as the CL-150, but only general language content.

Learning a language for personal purposes

Learning a language for personal purposes?

Transparent Language Online may be the option for you.

Although uniformed personnel also have access to the broader and deeper CL-150, those looking only to learn the basics of a language for personal reasons may prefer the simpler and more streamlined environment of Transparent Language Online. The learning functionality of both systems is similar, which promotes language learning by multiple family members and makes it easy for a parent using the CL-150 professionally to help a child who is using Transparent Language Online.
