The Swedish Association of Sign Language Interpreters (STTF) has a rich history that dates back to the mid-20th century. Initially, the need for sign language interpreters in Sweden was recognized by the Swedish National Association of the Deaf (SDR) during the 1950s and 60s. This period saw significant advocacy efforts to improve the lives of deaf individuals, including the push for professional sign language interpreters.

In 1967, SDR highlighted the necessity of sign language interpreters to the government, leading to the establishment of free interpreting services for the deaf in 1968. This was a pivotal moment as it indirectly acknowledged sign language as the first language of the deaf community in Sweden.

The first interpreter training course, known as the "course for cultural interpreters for the deaf," was held in 1969. This course marked the beginning of formal interpreter education in Sweden. Among the participants was Astrid Fredriksson, who became one of Sweden's first professional sign language interpreters.

In conjunction with this initial training, the Swedish Association of Deaf Interpreters was founded. This organization was later renamed the Swedish Association of Sign Language Interpreters (STTF) in 1983.

STTF is dedicated to improving working conditions and providing continuous professional development opportunities for sign language interpreters. Recognizing the crucial role interpreters play in bridging communication gaps, STTF advocates for fair wages, reasonable working hours, and supportive work environments.

In addition to advocating for better working conditions, STTF places a strong emphasis on professional development. They organize workshops, seminars, and training programs aimed at enhancing the skills and knowledge of sign language interpreters. These initiatives are designed to keep interpreters updated with the latest developments in the field, ensuring they can provide the highest quality of service to the deaf community.
