The Working Alliance Inventory of Supervisory Relationships (WAI-SR) was designed to evaluate the three factors--an agreement on goals, an assignment of tasks, and the development of a bond--of a working alliance between supervisor and trainee as proposed by Bordin (1983). The items for the WAI-SR were drawn from the Working Alliance Inventory and adjusted to reflect the context of the supervisory relationship. Results from practicum students enrolled in school counseling, counseling psychology, and clinical psychology programs indicated that the WAI-SR had adequate reliability. In the future, the WAI-SR may be used to gain a broader understanding of the importance of the supervisory relationship in the development of the counseling student, as well as to define the stages of a single supervisory relationship. The WAI-SR might also be used by a supervisor, throughout the supervisory process, to increase his/her awareness of the current needs of his/her practicum student, and to modify the supervisory process to meet the needs of the student, thus providing a favorable environment for change.
