Axelos/Peoplecert requires that candidates get the ITIL 4 Foundations certification before they can take an intermediate certification, so there is precedent to requiring certs to take another cert exam.@Rick Butler & @Greg Childers , i agree that having a firm prerequisite for certifications would be hard to enforce. But I would look to what others in the field are doing. One example would be the CISSP certification from ISC2. You can complete the certification exam. But if you lack the requisite experience and/or education. Your cert is 'put on ice', as they put it, until the prerequisites are met. A good middle ground.
