First of all, any student planning to enter a graduate school should take the following:

• statistics, both introductory and advanced
• a research methods class
• psychometric testing

    As for psychology courses that are particularly relevant to forensic psychology one should consider the following (be aware of the comments regarding which disciplines they would be especially relevant too)

• Social Psychology - this class is relevant to virtually all areas of forensic psychology.  Studies of violence and aggression can be of particular importance to both criminal profilers and correctional psychologists.  How people work together and react socially is of particular relevance to the police psychologist that work with, design programs for, and provide consultation to police officers.  Social psychology also has many implications in the court system, for example findings have show that certain personal factors can influence a jury's decision making processes.
• Abnormal Psychology & Personality Psychology - typically these are two different courses.  Both are of extreme relevance to those considering both careers in criminal profiling and correctional psychology.  Basically any area of forensic psychology that involves the interaction with criminally insane offenders will find that a strong background in abnormal personality is extremely important.
• Child Psychology & Developmental Psychology - again these at some schools may be two different courses.  In most circles it is believed that criminals (especially the most sadistic) are created not born.  Child and Developmental Psychology allows one to see how a child's personality is shaped, and how certain experiences can sometimes transform into future criminal behavior.
• Industrial Psychology - any psychologist working directly with a police force will often be asked to perform the tasks of an industrial psychologist.  In order to do this effectively one must be trained in that area.  Such psychologists would often be used to aid in the hiring of police officers, create work related programs in order to improve conduct/efficiency etc., and to solve certain job related problems/disputes.
• Behavior & Drugs - criminals often are found to be drug abusers.  Drugs, whether they are recreational or medicinal, can drastically effect our behavior.  Knowledge regarding the behavioral effects of drugs can be of extreme importance when painting a particular criminal profile or while dealing with convicted offenders in a correctional-psychiatric institution.
• Psychotherapy - psychology staff in correctional institutions will often have to provide psychotherapy to their clients.  Abnormal psychology courses will provide an introduction to such courses but a more specific class (such as a 4th year psychotherapy course) would be a strong asset.
• Motivation - the study of why we do the things we do.  Understanding the motivational processes behind our behavior has key implications towards forensics.  This class would be particularly relevant to corrections and profiling.

• Political Science Department - Introduction to Criminal Law:  Anyone who is working in the criminal justice system can benefit greatly from a thorough introduction to the criminal law system within which they will be working.
• Sociology Department - Criminology:  criminology is a very diverse field that can be of particular interest to the forensic psychology major.  Here you can find discussions on criminal patterns, as well as a comprehensive look at the theories regarding criminal behavior and violence.
• Anthropology Department - Forensic Anthropology (may be listed under special topics in medical anthropology or Human Skeletal and Dental Biology):  Of particular interest to prospective criminal profilers, forensic anthropology is particularly relevant to crime scene analysis.  No profiler should ever be without a background in this field.
