And there are undeniable benefits to Certification training. According to Stephen Rose, a Georgetown University research professor, salaries jump about 20% for certificate holders when compared with workers with high-school diplomas only.
For some fields, certificates' training success can be amazing. For example, in the field of computer and information services, male certificate holders who work in the field earn more money on average than 72% of men with associate degrees and 54% of men with bachelor's degrees, with the breakdown being 75% and 64% for women.
Employment rates for people with a high school diploma are 8.3% as of 2012. For individuals without a diploma, the unemployment rate is significantly higher at 12.4%.
