Hi there.

"What can I target after CSA?"

That's really up to you. Which areas do you want to focus on, or what is important for your company? And is it about the training or the certs? For a lot of customers certs are totally useless (the trainings themselves might be useful!), while for consultancy companies for example its a must. Etcetera.

There are also (paid) courses without certificate which might be very useful. For example, I'm more on the technical side, and I liked the Scripting Fundamentals course a lot, though it does not come with a certificate.
