There are things that are equivalent. The issue isn't that there aren't credentials that could be trusted for software developers, so much as no one interviewing for software developers cares.

My degree was an ABET accredited engineering degree that required practical software development skills (including soft skills). Outside of interviewing in my hometown, no one knows that or cares.

The software industry tomorrow could easily adopt the internships and test/certification requirements of a profession like medicine or engineering. The industry doesn't seem inclined to do so, however, for a weird variety of reasons and excuses, and seems for the most part overly satisfied with trivia questions and whiteboard problems.
