EMS was founded in 2004 and is based in Melbourne, Australia. Our preferred tools for day-to-day analysis work include and RStudio. Aside from our general data processing capabilities, we provide specialist support for educational measurement projects in areas such as instrument development and validation; complex sample designs; test equating; and student ability estimation. This includes the provision of software packages so clients can perform these tasks internally on their own. Our analysis is always conducted in a reproducible manner so that it can be independently replicated. Further details of some past EMS projects can be found here.

If you would like to find out more about educational measurement as it is applied in practice we recommend Educational Measurement for Applied Researchers (Wu, M., Tam, H. P. and Jen, T., 2016) (ISBN 978-981-10-3302-5). If access to the book is an issue there is also Applying the Rasch model to psycho-social measurement: A practical approach. (Wu, M. and Adams, R., 2007). These texts provide a good overview of the type of psychometric services we can provide.
