[2] The conference had a large geographic footprint, including schools in nine counties (Brown, Door, Kewaunee, Manitowoc, Oconto, Outagamie, Shawano, Waupaca and Winnebago).
[6] Two Rivers moved from the Eastern to the Western Division in 1949,[7] and the conference added two schools in 1950: Kimberly and Seymour.
Growth in the Green Bay metropolitan area and the opening of new high schools drove expansion of the NEW Conference in the 1950s and 1960s.
Preble High School was opened in 1955 and joined the NEW Conference the next year, bringing membership to ten.
[13] The Northeastern Wisconsin Conference would continue with twelve member schools for the next four years before a major realignment occurred in the region.
