When the Oregon High School Athletic Association, now called the Oregon School Activities Association, was formed in 1915, there already were several high school leagues in the state. One of these, the Portland Interscholastic League, is still in existence. The OSHAA has used the leagues as the basic component for that organization ever since.
The first district tournaments held in wrestling were in 1941 and 1942, before the OHSAN OSAA took over sponsorship of the state tournament. The districts were special ones that followed, somewhat, geographic lines. The first year, two wrestlers per district qualified for state, the second year only one. That makes 1942 the only year only one wrestler per school could make it to the state tournament. In all other years, two wrestlers could conceivably make it to the finals of the state championships.
In 1950, two years after the OSAA took over jurisdiction of the state tournament, district tournaments were found to be necessary. Four special district were formed. with four wrestlers per district qualifying for state. In 1952 and 1953, district Four was divided in two, a southern half and an eastern half, with two wrestlers from each qualifying for state.
In 1954, the OSAA expanded the competition to eight special districts, but limited the entries to two per weight, thus keeping the tournament at the same size. In 1956, the PIL entered wrestling competition en masse, and became the first league to also be a district.
Before the 1959 tournament, a major advancement in the state structure was made when the larger schools were broken off in to their own state A-1 championships. All the A-1leagues became districts, as well. At the A- 2& B level, the special districts continued, in most cases. Changes were made from year to year with a mixture of regular and special A-2 & B districts. In some cases, sub districts were held that were league championships qualifying wrestlers for the district. Leagues known to have done this were the Sunset, Coast, Rogue Valley, Umpqua Valley and Trico.
By 1969, the small school tournament had become solarge that it was split into separate divisions for A-1 and B schools. The A-2 leagues became districts for wrestling while the B schools qualified through two separate special districts. Gradually, more and more B schools (now Single-A) have taken up the sport, and the district alignment has grown and changed from two district to four.
In 1990-91, the names of the three classifications were changed from A, AA and AAA to 2A, 3A and 4A Besides the name change, there was little effect on wrestling alignments.
