Latin American Montessori Bilingual Public Charter School

Latin American Montessori Bilingual Public Charter School is a public charter school in Washington, D.C. It operates in two buildings in the Northwest and Northeast quadrants of the city: one on 14th Street in Northwest's Sixteenth Street Heights and one at the corner of Perry Street and South Dakota Avenue in Northeast's Brookland neighborhood.

It is overseen by the District of Columbia Public Charter School Board. As a charter school, LAMB is a nonprofit organization, funded by local tax revenue, and subject to some, though not all, of the same standards as traditional schools that are part of the District of Columbia Public Schools. Its admissions are based on a lottery system that takes into account preferences for siblings of current students and children of school faculty and staff.

Curriculum
LAMB teaches a curriculum based both on the Montessori educational approach developed started in 1897 by Italian educator Maria Montessori and on Spanish-English bilingualism.

Students from preschool for 3-year-olds through grade five attend the school.

History
LAMB was launched by the Latin American Youth Center, a Washington, D.C., non-governmental organization that serves young Latinos.

The school first had its application as a charter school approved by D.C.'s Board of Education in 2001, six years after Congress passed the District of Columbia School Reform Act of 1995, setting up the system for charter schools in the nation's capital. LAMB started classes in 2003 in Our Redeemer Lutheran Church, a church in Northeast Washington, while it looked for a long-term home. It had 57 students at the time.

The school moved to the Military Road School on Missouri Avenue in 2006, its first long-term location. It renovated the building between 2008 and 2009 and added office and classroom space, while preserving the historic schoolhouse.

In 2013, LAMB established a second location, sharing a building with the Perry Street Prep charter school on South Dakota Avenue in Northeast Washington. The building formerly housed the public Taft Junior Elementary School before the city closed that school in 1997 due to low enrollment.

LAMB opened its third location in 2017 on the former campus of the Walter Reed Army Medical Center in Northwest Washington. The school shares the former medical center's Delano Hall with the District of Columbia International School.

In 2020, LAMB moved to a newly renovated building at 5000 14th St. NW. The building was most recently used by the Kingsbury Center, a school for children and adults with learning differences, before it closed in 2019. As of 2020, the school is not conducting in-person instruction due to the COVID-19 pandemic. But when in-person learning resumes, only the new 14th Street location and the South Dakota Avenue location are expected to be used.

The move to 14th Street had been planned since 2017, but it had been delayed due to opposition by some neighbors.
