We must understand administrative data as a repository of information on the functioning of public or private policy. They serve us to follow up on these policies.

In general, it is advisable that our indicator be SMART (Specific, Measurable, Achievable, Relevant, Time-bound).

Let's see if the School Attendance indicator meets the characteristics of a SMART indicator:

Specific: attendance refers to the specific action of attending or not attending classes.

Measurable: it is possible to determine on a daily basis how many children attend school.

Achievable: it is relatively easy to measure. It is sufficient to take a daily list by classroom, for example, of who attends and who does not.

Relevant: with attendance we measure directly an indicator that is relevant to evaluate the school's performance.

Time-bound: we can calculate the daily attendance or number of days in a month, semester or year. Calculate a percentage of attendance for a given period of time.
