Sijin Joeseph's Programmer Competency Matrix is perhaps more general than you are looking for, but relevant.

There's some precedent for this in the contractor-marketplaces like Odesk. They'll have a list of dozens of skills/topics that a contractor can prove their knowledge of. They give them a score based on their performance relative to the larger group who has taken the test. You can see the tests here: https://www.odesk.com/tests (but you'll need to create an odesk account first).

There are also a number of coding-challenge sites where you can show off your skills and get ranked, like codeeval.com

Both these types of scoring systems are just rough heuristics though. Since full-stack development uses a lot of "soft" skills like organization and creativity, you'll never really get the full-picture from these kinds of objective battery tests.

This may not be exactly what you want, but may be good start http://www.sitepoint.com/full-stack-developer/

This is actually a good post, and it would be very useful to have some sort of repeatable way to compare your own skills to the skills requested by a certain industry/market.
