The NVST (Nederlandse Vereniging voor Stottertherapie) is an association of Dutch speech and language therapists, with additional certification in the field of stuttering and cluttering.

The NVST was founded in 1987 with the aim to increase the knowledge about stuttering and to improve the quality of stuttering therapy in the Netherlands.The quality of its members is monitored by an internal quality control system that has been recognized by official Dutch healthcare institutions.

Since 2015 the NVST has become a partner of the CESS to improve and maintain the quality of care to people who stutter at a nationally and international level.
