The kanji 校 is a phono-semantic compound (形声文字, keisei moji). It combines the phonetic component 交 (kō - meaning "cross" or "intersect") with the semantic component 木 (ki - meaning "tree"). The original meaning may have related to the idea of a place where trees are marked or crossed, then developed to mean a gathering place or a place for comparison or checking. Over time, it evolved to represent a place of learning and education, taking on the meaning of "school" and "institute." The use of 交 (kō) here suggests the idea of intersecting or comparing information to learn and verify.
