There are numerous MBA rankings across the world and even considering just online MBA's, there are various ranking providers to choose from.
For both online and full MBA programs, the two leading ranking providers are considered to be the QS rankings and the FT rankings.
Both sets of league tables consider the global perspective, so you know that the table-toppers are held in the highest esteem across the world. The FT rankings also measure the impact of an MBA on prospective salaries - this is achieved through an alumni survey.
The monetary return on investment is an important supplementary consideration, along with study mode, cost of study and business school and/or program accreditation. Further information on accreditation and the role it plays can be found here.
Here at onlineMBAonline.com, we have merged the FT and QS rankings together to form a 'rank of ranks'. The results can be seen here.
