As an interesting note, starting last year TSA began a massive reorganization and transformation period. It hit it's 10 year anniversary and proceeded to begin a process of evaluating all it's various offices. The thing to remember with TSA is, unlike MANY of the agencies in the US, it's a relative baby. An organization made up of disparate parts of many other organizations, spun up in weeks/months and only just recently hitting a decade in terms of it's age. There's still a lot of bugs to be worked out and tweaks to be made in terms of making it run as efficient as possible (relative to any government agency running "efficiently).
One of the things involved in that reorganization was the creation of the Office of Training and Workforce Engagement. An offiec largely aimed at streamlining and standardizing training that occured within TSA. A lot of the training previously had guidance from a headquarters stand point but had a lot of of reliance on the individual airports training staff in terms of how things worked. The new office has been looking at ways to improve training, create a more standardized and unified form of training, find better ways to monitor and test for quality training results, and other such things.
Part of the process was looking at the best practices put into play by one TSA office which had it's own in house training division, and whose workforce was exceptionally well training. The new Assistant Administrator of OTWE is actually the former Deputy Assistant Administrator of the office in question. Many of the leadership in the new Office of Training also came from that office. So there's definitely a desire, focus, and action within TSA to improve Training across the entire organization.
The other thing that's being done...again, actually borrowing from a program that was done successfully in a particular office of TSA....is attempting to roll out a program over the entire organization aimed at improving and reshaping the culture within the agency in terms of accountability, focus on the mission, and workforce empowerment. It takes some time for corporate cultures to be changed and for those changes to infiltrate all levels, but over the few years since the program was done in the individual office there has been noticed improvements, and hopefully a similar trajectory is seen when implimented agency wide.
