Developing a Indian Student Psychology assessment test

I am looking to hire a freelancer to develop an Indian Student Psychology assessment test targeting middle school students for measuring psychological traits. This assessment should be delivered online and customized to the age group it's targeting. The desired test should be scalable and easily replicable. The said assessment will enable us to measure the results for academic progression or additional resources needed. The successful candidate must be experienced in the field of psychology and should have extensive knowledge in developing assessment tests for the online platform.
