During the protracted development process, Schweizer
Aircraft was aware that the 1-34 would be overtaken by the changes in class rules and also by the performance of the newer European fiberglass sailplanes, but continued development of the SGS 1-34 anyway. The company identified that there was

By the time the 1-34 was introduced it was no longer competitive in the
Standard Class, but has proven very successful as a club aircraft, being a great "step-up" sailplane for post-solo students and accomplished pilots.

Standard Class rules. Developing and testing these proved expensive and time-consuming and this also extended the aircraft's development time.

Standard Class rules had changed to allow essentially unrestricted sailplanes with a 15-metre (49.2 feet) wingspan.

The 1-34 was designed over several years to spread out the development costs. At the time the design work on the aircraft was started the
Standard Class was new and described a very simple aircraft with
