Nokia (Alcatel Lucent) MPLS Certifications - Are they worth it?

I have been working on a new project of designing a new private MPLS infrastructure utilizing Nokia (legacy Alcatel Lucent) equipment. We recently completed our design phase for the first 300 sites or so and just kicked off some basic training about the SR-OS platform and their NSP management platform. The training has been hit or miss for the level of detail around MPLS that I am looking for and has been lacking in many other important areas such as QoS. All of our classes thus far have had a mixed audience with a few network engineers but mostly telecom technicians that run our SONET and TDM transport equipment. Have any of you gone through their SRC courses or training? Is it worth taking the SRC (certification) level courses compared to taking some of the standalone courses that are not “SRC” courses?

Thanks for any and all input!
