As I have said in the appropriate sub-forum on Certifications ... a "certification" is simply a quasi-diploma or certificate of completion for a technical training program.
It is
not a Golden Ticket.
Therefore, I suggest that you approach "technical training" as any knowledgeable consumer would: what do you want to learn, and what is the best classroom-environment in which to learn it? Consider all options, including your local Community College.
I, myself, wrote and taught night classes for many years. They were, if i say, very advanced and challenging courses, and the
adult students (most of whom
had baccalaureate or higher degrees) wanted it that way. Some students were not doing it "for a grade," even though I encouraged them to take the tests anyway, as part of the instruction. I have also recently become involved once again in mentoring.
"The most general" might not be "the most appropriate" for
you, in
your situation, to reach
your educational goals. This is a product that you intend to buy. Choose wisely. Examine yourself.
Furthermore: express your interests to your
employer. Many departments have, or can obtain, money for staff-development. It is in their best interest, not only to have more-trained employees, but also to satisfy those employees' curiosity and desire for self-improvement if those employees express such a thing. (And, guess who just became "more noticeable" when someone needs to be promoted?)
