Microsoft Professional Program Now Offers 5 Different Online Degrees

It’s been about 1.5 years since Microsoft first announced the Microsoft Professional Program. Basically, the Microsoft Professional Program (MPP) is a cross between an Online Degree and a Multi-Exam Certification. It’s a good move by Microsoft to provide a better training path than certifications, while simultaneously working to fill the skills gap that traditional degree programs have difficulty filling. Essentially, it’s a good cross between the two paths, providing yet another great non-traditional alternative to education and career advancement. Plus, now the Microsoft Professional Program offers 5 different “degree” tracks to choose from! Read More
