Certified to Rock
CertifiedToRock.com was created to allow community members and employers to get a sense of someone's involvement with the Drupal project.
Certified to Rock (aka CTR) uses a custom algorithm that gathers publicly available information from drupal.org, which is then distilled into a score on a scale from 1 to 11. The algorithm produces scores for site builders, developers, documentation writers, themers and anyone else who is active on drupal.org. We've also designed the algorithm to consider how successful the person is at engaging with the Drupal project.
The only barrier to entry is involvement on drupal.org: once you have a computer and internet connection, you can start contributing work that will increase your CTR score: patches, code reviews, documentation, modules, themes and support.
Why Certified to Rock works
-
CTR scores don't get stale. As long as one's participation continues, their score will eventually go higher.
-
Unlike other certification programs, CertifiedToRock.com's scoring is free and doesn't require any time commitment beyond normal interaction with the Drupal project.
-
Someone with a higher score is more likely to be respected within the community, and this usually means they are more likely to get assistance from the Drupal community via IRC or issue queues when they need it.
The implementation
Ben developed the code, Evelyn worked on the design and Carl implemented the custom theme. CTR was built in early 2010 on a Drupal 7 alpha release.
Updating Certified To Rock
As the project matures, we are developing more frequent score updates and adding new individuals.
Another area that has required some iterative improvement is the secret algorithm used to calculate scores.
What people are saying
The GVS team loved this:
Several people are proudly displaying their CTR presence on their personal sites or drupal.org profiles.
Companies such as Lullabot and Grammys.com are asking job applicants for their CTR score, if they have one. We think it's great that a CTR score can help support a job application, but not guarantee a job nor exclude anyone.
