K–8 school
type of school in the United States

K–8 schools, elementary-middle schools, or K–8 centers are schools in the United States that enroll students from kindergarten/pre-K (age 5–6) to 8th grade (up to age 14), combining the typical elementary school (K–5/6) and junior high or middle school (6/7–8).
As of 2007, many American private schools have K–8 configurations.
History
In the late 19th century and early 20th century most American elementary schools had grades 1 through 8. The "junior high school" concept was introduced in 1909. As time passed, until the 1940s, junior high schools increased quickly. The installation of junior high schools was made in order to provide more academic and social opportunities for adolescent students prior to entering high school. By the 1960s many U.S. school districts separated the elementary and junior high school levels, with seventh through ninth grade students at junior high school. As years passed, the model changed to middle schools serving grades six through eight.
By 2007, in some communities, schools in areas where academic performance at the middle school level was low were converting back to the K–8 model in an attempt to increase academic performance. By 2008, many urban school systems converted middle schools to K–8 schools.

Why this record matters
The phrase “type of school in the United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Mar 30, 2026. The linked authority identifier is Q5358885. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2007, 1909 and 2008.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
