Letters of recommendation. Three letters of recommendation are typically required. Ideally, the letters should be from faculty members or professional supervisors with whom you have worked closely. At a large university it is uncommon for students to have close working relationships with professors in large lecture courses. For this reason, it is doubtful that a letter of recommendation from a professor of a large lecture course would be very effective.
Students often obtain letters of recommendation from faculty whose research they have assisted.
It is often the case that undergraduates have more contact with graduate students working in the respective labs. Although the graduate student supervising the lab may be able to write a glowing letter of recommendation, it is better to ask the faculty member in charge of the lab to write the actual letter of recommendation. Faculty members names are better known throughout the psychological community and carry more weight. Students may also participate in Internships in Psychology. Participating in internships or practica enables students who are interested in clinical or consulting work to get some hands-on experience.
