NCEES tried a few years back and developed such a curriculum but there wasn't enough interest so they got rid of it. IIRC, something like a total of 6 people were certified as a software engineer in the last year it was available. I don't see required licensure for software engineers happening unless 1) it's driven by employers or 2) it's driven by regulators. I don't see #1 ever happening because it's asking the employers to give more leverage to their employees. I'd personally like to see #2, at least on certain safety critical applications.
