If the class date is less than 1 week away, the class has likely been closed to enable the students to complete the on-line work. There may be a few open spots. You can send an email to the SDI to see if any spots are available. The SDI will check availability and make sure that you have time to complete the on-line work before facilitating your registration (if space allows). If the course is more than 1 week away, the course is full (the number of students is set by the host and not Western PA Refs), choose a different course.
