To date, UP NISMED has facilitated lesson study groups in several public high schools within the Metro Manila area. The first model of lesson study implementation was in 2006 and the second model, a refinement of the first, was conducted in 2010.

Batch 2007 was attended by teachers from Rizal High School in Pasig, Balara High School in Quezon City, San Vicente Elementary School and Krus na Ligas Elementary School, both in Quezon City. From these, a total of six high school lesson study groups and ___ elementary lesson study groups conducted lesson study in varying degrees.

For its second batch of lesson study, NISMED concentrated in one school in Pasig - Sta Lucia High School. As in Rizal High School, one lesson study group was organized for each year level involving all the teachers in the year level.

In 2011, NISMED conducted its first lesson study in a school outside Metro Manila with the teachers of Ligao National High School (LNHS). Lesson study was also introduced to the math and science teachers of Nueva Ecija High School last February 2012.
