For classroom and virtual mode of tuition, I can vouch for Ebecks System, HSEQ 360 and Edward Debrah Consult as they continue to show dedication and a high level of professionalism as safety professionals themselves who understand the value of investing in continuous professional development, hence providing value for money. You won’t waste your investment, and you can be guaranteed a pass.
For online mode of tuition, I started my NEBOSH Courses with SHEilds from 2013, as I preferred their self-paced tuition and the 3-month installment that made it easy on my pocket as a beginner. As a matter of fact, when I was given GHS 4,000 by my dad for my supposed classroom tuition, I rather used it to register for IGC and IOGC e-learning and then used my own salary to register for the exams. I considered using the same for the Diploma because of the long duration of the program. I needed a tuition provider that could stand the test of time with less risk for my long term goal.
There are various other promising ones but just take note of the bad nuts. I lost money for 2 Lead Auditor Courses because the tuition provider did not deliver the training certificate. That was Litac Africa, so always be careful and check their online reviews on Trustjet before parting away money.
