From another board (my emphasis added):
Good Afternoon,
Thank you to everyone for the great questions and discussions concerning the CT, IT and IS ratings.
For the first time in a long time, we are at capacity across the NNFE ratings. Big Navy is actually in a draw down and NNFE is still growing. This has been a challenge for the NNFE ECM and OCM, but we have been successful in fencing cuts across our ratings and designators. We are fortunate to have a lot of publicity with the stand up of US Fleet Cyber Command/TENTH Fleet and the growth required to build the cadre of Cyber Forces to meet tactical and national Cyber mission requirements.
As far as traditional ways of joining the ranks of the Cyber Forces as a CT, IT and IS - those ratings are closed until at least next summer (2010). That being said, referencing the the comments I saw today concerning interest in the IS rating. The only way into the IS rating at this time, is if you are a reserve IS rated Sailor wishing to come back on active duty or a reservists in another rating who is willing or able to convert to IS in the reserves and followed by going back to active duty as an IS. The IS TECHAD is not accepting anyone into the rating unless they have already completed IS A School.
I will continue to keep you posted on health, retention and advancement opportunities across the CT, IT and IS ratings.
Have a great day.
