Grant application system ISAAC

NWO uses as application and reporting system: ISAAC. Research proposals can now be submitted through this new application to NWO. With the new programme, applicants for research funding are able to track their application in the assessment process. ISAAC is also used for submitting reports on ongoing research projects funded by NWO.


Go to to create an account and to log in to ISAAC. If you already have a login name and password for the previous system Iris, than you should log in to ISAAC with the same data. For some accounts the old login details cannot be converted. In that case, you need to create a new account. NWO will transfer your project history from Iris to your new account.
