The Go/No-Go evaluation (scheduled approximately 1 year after the start of the PhD project, but no later than 18 months after the start of the PhD project) is mandatory for PhDs of various PE&RC partner institutes but is highly recommended for all. It is a decision on whether the PhD candidate may continue with his/her PhD project or not where the decision is based on the evaluation of progress, knowledge, and insight of the PhD candidate in the project, but also on the status of the admission criteria (e.g., approval of the project proposal, proficiency in English), and on the general process.
For the evaluation, a Go / No-Go form can be used, but this is optional. In practice, all groups affiliated to PE&RC, and even all individual PhD project teams are free to decide how to structure the Go / No-Go procedure. Therefore, it is recommended that at the start of the project, the PhD candidate discusses the Go / No-Go procedure and criteria of evaluation, and the time-line involved, with his/her supervisors. An example of a way to set up such a procedure can be found here. The latest version of the Go / No-Go form can be found here.
In case of a No-Go, the PhD project will be terminated. In both cases (Go or No-Go), the graduate school needs to be informed. In some universities (e.g., Wageningen University) the Go / No-Go evaluation is a formal admittance criterion to the PhD programme, so without registering the outcome of the Go / No-Go evaluation with PE&RC, a Wageningen University PhD candidate cannot defend his/her PhD thesis. The graduate school needs only to be informed about the outcome of the evaluation and the date on which the decision was taken. The Go / No-Go form itself is confidential and only to be shared between the PhD candidate and his/her supervisors.
