Note: This is a beta exam

To assist Puppet Labs in establishing exam scoring for the Puppet Developer Certification, we are inviting Puppet developers to take the beta version of the Puppet 301 – Developing for Puppet Using Ruby exam. The beta version of the exam is slightly different than the final exam, as we ask candidates to test more questions than what will be presented on the final exam. Candidates may achieve certification after taking a beta exam if it is determined that they meet the passing score once one is established. However, exam scoring will not be immediate and candidates should expect to receive results approximately 6-8 week after beta testing has closed.
