MetaMetrics and LEDDI Expand Partnership to Strengthen English Literacy in South Korea
Policy1 min read
MetaMetrics, the maker of the Lexile reading measure, and LEDDI Corporation, a Seoul education technology company, have expanded their partnership. LEDDI is now the official exclusive distributor of Lexile Express Tests for reading in South Korea.
What happened
MetaMetrics and LEDDI announced a bigger partnership on November 1, 2026. Under the deal, LEDDI will sell MetaMetrics' computer-based and fixed-form Express Tests in Korea. These tests check how well students read English. LEDDI will also offer tools that measure how hard a text is, so teachers can match students with reading material at the right level.
Key facts
- The Lexile Framework for Reading is used by more than 40 million students each year.
- More than 100 million pieces of content have been measured with the Lexile system.
- LEDDI's platform has more than 4,500 English books, plus AI-based worksheets, reading tests, and class management tools.
- The platform is aimed at elementary school students and their teachers.
Background
The Lexile Framework gives reading ability and text difficulty a score on the same scale. A Lexile score for a student shows what level of text they can read. A Lexile measure for a book shows how hard it is. Because both use one scale, teachers can match the right book to the right student and track progress over time.
Why it matters
Many Korean students learn English, and parents and teachers want clear proof that reading is improving. With this deal, schools in Korea can use a well-known, research-based system instead of guesswork. MetaMetrics' CEO said that trusted measurement is needed to help English learners build the skills they need to succeed.
What to watch
- How many Korean schools and teachers start using the Lexile Express Tests through LEDDI.
- Whether student reading scores rise over time, as the partners plan to monitor.
- How LEDDI's platform grows beyond elementary school students.
