Despite several initiatives to integrate accessibility to the Software Engineering (SE), in practice, little is known about both the participation of people with disabilities in the phases of the software development process and the methods used. Inclusive SE is a challenge and many research opportunities may be identified. In this scenario, our objective was to identify accessibility guidelines for questionnaires, an extensively used technique, aiming at the inclusion of deaf people in many activities of the software development process. We believe initiatives like these guidelines are a step towards the inclusion of deaf people during the whole software development process and could further contribute to the accessibility of software systems.
