Survey Likert scales with degree-of-agreement response categories are commonly fielded. Whether to offer a neutral response category for such scales is not well informed. Using data from a randomized survey of teachers and an Item Response Theory-based analytic approach, RAND researchers examine the utilization of a neutral response option when offered and discuss potential changes to conclusions depending on neutral category presence.
