Social
Casterton Secondary College is a single campus, Year 7 - 12 school. The 2009 enrolment is 206 students. Enrolments have briefly increased, but in line with the local trend are expected to remain steady in the near future. Our students come predominantly from rural or related backgrounds and 37% of our families are EMA recipients. There are low levels of students born oversees and very few students of Koori background.
The staff of the college has changed significantly in recent years. We currently have 25 teaching staff (including the Principal Class), with part-timers which equates to 24.6 effective fulltime positions. There are 14 non-teaching staff including integration aides. Of the teaching staff, 5 teachers have less than five years experience, 12 are Expert Class and a further two are Leading Teachers. The remainder are in the graduate or accomplished categories.

Environmental- grounds and facilities
The College grounds are of a very high standard. In 2002-3 the College had a major upgrade to the top wing. In addition to upgrades to the top wing, the College has successfully attracted funding to refurbish the sports centre, upgrade its integration facilities, create a new media centre, a new indoors dining facility, new tennis courts, upgraded the careers centre, and created a year 7 staff room next to the refurbished student homerooms. Its woodwork and sheet materials rooms have new equipment. We have purchased a school bus and shade cloth for our Year 7 area. We have recently received funding of $125,000 as part of National Schools Pride for Grounds Refurbishment.  A submission has also been made under the National Trade Training Centre initiative for a significant refurbishment of the Agriculture, Home Economics and Technology (Metals) area.
