Are there specific certifications or additional training that would help me get a job in applied psychology fields?

It depends! Desired skill sets can vary based on the needs of the organization. A great exercise is to look up potential jobs of interest ahead of time. Do some internet searching on key words, and see what jobs pop up! You can then track required qualifications posted in job ads of interest. They should tell you if there are specific competencies that would be helpful. To help track this information, you can make a copy of this spreadsheet and track information from jobs that you’re interested in. As your sample grows, you can look to see if there are common qualifications of jobs you are interested in. We are all limited in resources–focus on those competencies most commonly required for jobs you are most interested in.  This is a great road map for competencies to consider working towards!
