Saber 11 results of every Colombian municipality by the socioeconomic stratum of the students' homes, per exam period, 2010 to 2022 (Colombia's end-of-secondary exam, run by ICFES): students who sat it (each counted once) and their mean global and per-area scores. Stratum is `1` to `6`, `sin_estrato` or `no_reportado`, as each student reported it. Filter by `territory_code` (5-digit DIVIPOLA municipality of the school or 2-digit department), `year`, `period` (`yyyy-1` or `yyyy-2`) and `stratum`. Served by Croma (`as_of` says how current the data is).

**Dataset endpoint**: answers from the whole source in milliseconds and carries `as_of`.
