366:1 includes management and combined positions. Public sector (at least city, county, school, state) tends to have more systems and less techs. My shop is a public sector shop.

Our system/facility counts:
~1100 desktops/laptops
~45 network switches
~10 physical servers
~10 virtual servers
4 storage systems
1 managed wireless system
7 schools, 4 admin buildings, ~2300 students, ~500 teachers/staff

Our personnel:
1 manager/DBA/server admin/network admin (combined position)
2 FTE tech support on staff now
1 open tech support position (open since September, and open from Feb-August prior to that)

Our biggest problem is we can't pay nearly what a corporate environment can offer, even though there tends to be far more individual responsibility in our positions. If I chose to work in a corporate environment, I could easily be making twice my current salary with my experience, education, and knowledge. But then I'd be bound by constraints the education field doesn't have.

The job situation in our area is also the reverse of the rest of the U.S., if you want a job (even one that can pay 6 figures), you just need to have a pulse, pass a drug test, and be willing to work on an oil drilling rig. They even have tech related jobs that pay in that range.

We run a software/hardware management system and centralized imaging system. It saves us a lot of time/hassle, but still can't take the place of one or two people, especially a higher-level server/network admin or DBA.

When we compare to other schools our size and larger in our state, those schools tend to have a better ratio of systems:techs.
