When we reject an application, the rejection email contains details about why the application was not successful and usually tells applicants that they must wait 6 months before submitting another application for the same journal to us. Why do we do this?
One reason is that it is an attempt to discourage repeat applications, made in haste, and we get many, many of those. Repeat and duplicate applications clog up the system and take our dedicated volunteers and team away from those applications which need some time spent on them. (In 10 months alone, DOAJ received 221 duplicate applications!)
The other reason is that many of the recommendations that we make in our rejection emails, recommendations made to help journals meet our criteria, take time to implement. Adding words to a website isn’t enough. Changes need to be implemented properly, communicated to stakeholders, tested, and managed. Some changes will require other parties to implement changes too. This all takes time. After the 6 months has passed, we welcome a new application but we ask that the journal website demonstrates very clearly that our recommendations have been put into practice and our editorial team will be very careful to check that all our recommendations have been implemented.
