Pros
Harvard has excellent benefits: healthcare, education etc. I also worked with a wonderful group of people at PPE. Most of them became really good friends and most really worked hard. We had a lot of work so I learned how to effectively manage time and I can handle a lot of work well. I wouldn't trade this experience at all because it made me a better employee.
Cons
Overall the Harvard Graduate School of Education does not seem to pay its employees well at all. Also Programs in Professional Education (PPE) in many ways was not a good place to work. The office runs high quality professional development programs for leaders in education but is understaffed, has a high ratio of managers to staff and works its employees unfairly hard. The turnover rate is extremely high. Many people I know are like me and say they are glad they had the experience because it did make them better workers but did not liked working there. Unfortunately I wouldn't recommend working in this particular office which is too bad because they do good work
