Education industry statisticians

I work as a teacher in a junior high school in my country. I intend running data analysis on the activities of the school where it concerns education and teaching.
I use R software. I understand statistics on the average.
My question: I am looking for guidance on how to go about becoming what I described above. I have searched extensively on the Internet and fortunately I found this forum.
I work in a private school which is different from public schools but to remain in business we need stats knowledge of school activities. I found a document on the net that details a little of the knowledge I'd like to analyze.
Could someone tell me where to start on education statistics: resources, clubs etc.
Thanks. I attached the document I found on the Internet.
