The Education Commission set up in 1964, under the chairmanship of Dr. D.S. Kothari (normally referred to as the Kothari Commission) produced a report after two years of study. The report had described the idea of school complexes. The District Primary Education Program web site describes the concept of school complexes as mentioned in the Kothari Commission Report as follows:
The concept of school complexes was developed in Kothari Commission Report (1964-66). It is based on the assumption that High and Higher Secondary schools have better laboratory and library facilities, which can be utilized by the primary and middle schools. These schools have also better qualified and trained teachers; they have larger and well-developed playgrounds and games materials. Five or six primary and upper primary schools, as per convenience, may form a complex and get their academic and administrative support from the nodal secondary/senior secondary school. The attached schools in the complex, may arrange co-curricular activities, give better exposure to their students at the thus formed school complex rather than taking up the matter at block or district level. In case of temporary absence of the teacher due to illness, the school complex head can provide a substitute from a neighbouring school. A large number of academic issues and problems can be discussed at the school complex level by arranging a meeting of all the teachers or otherwise. Thus many states have evolved their own guidelines and formed school complexes.
The school complex model is very similar to the model I described in an earlier post. What I called the Central Unit (CU) could well be the nodal secondary/senior secondary school and the Local Units (LUs) could be the primary and upper primary schools that are attached to the CU. But I don't know if the school complex concept has been implemented anywhere over the past 35 years since the Kothari Commission Report came out. If anyone knows something about this, please do let me know.
Another thought that struck me was that the private schools that are being set up with substantial investments by various corporates like Reliance, Birlas and various other organisations involved in education could possibly become the CU and set up satellite schools themselves to leverage their infrastructure better. Need to think this through a bit more and try and write up a concept note on what a private school can do.
