“I worked with Thomas International throughout 2013 on a research project to update the Personal Profile Analysis (PPA). I was impressed with the commitment of Thomas' Psychology team to constantly update their tests to ensure that they're as psychometrically reliable and valid as possible. We analysed Thomas' past data from hundreds of thousands of test administrations and then followed that up by collecting data from thousands more participants on some new potential questions. The Psychology team were both professional and also fun to work with and I continue to enjoy consulting for them.”
