Here's a brief look at how the YAIAA came to be:
The Laurel Conference, which included Central York, Dallastown, Littlestown, Susquehannock and Kennard-Dale, plays its final season of football. York Suburban played its first varsity season as an independent.
The York County Interscholastic Athletic Association is founded with nine football teams: Central York, Dallastown, Kennard-Dale, Littlestown, South Western, Spring Grove, Susquehannock, West York and York Suburban. It's the first year of varsity football for South Western and Spring Grove.
Red Lion, from the Conference of Roses, and Hanover, from the South Penn Conference, join the YCIAA, bringing the total to 11 teams.
Both Kennard-Dale and Littlestown leave the league. Kennard-Dale doesn't play football again until 1976. Littlestown plays an independent schedule before joining the Blue Mountain League.
Vo-Tech (now York County Tech) increases the league's total to 10 teams.
Dover makes the YCIAA an 11-team league again by coming on board, and the league is split into two divisions.
Kennard-Dale comes back to the league, and Eastern York and York Catholic become the 13th and 14th teams to join the league.
William Penn joins its neighbors in the YCIAA, coming from the Central Penn League.
Delone Catholic, Littlestown and New Oxford all come to the league, now known as the York Area Interscholastic Athletic Association, from the Blue Mountain League.
Bermudian Springs and Biglerville leave the Mid-Penn Conference to join the league now known as the York-Adams Interscholastic Athletic Association. Fairfield, another Adams County school, also comes on board after completing its first varsity season as an independent.
Northeastern becomes the 22nd varsity football program in the YAIAA. It is the last public school in York or Adams counties to launch a football program.
Gettysburg leave the Mid-Penn Conference to join the league, becoming the 23rd varsity football program in YAIAA.
