Table A.1: Scotland's score in previous PISA surveys, together with comparison with 2015
|Mean||S.E.||comparison to 2015|
H: higher than 2015, S: similar to 2015, L: lower than 2015
Comparisons in science are possible from 2006 (the first survey when science was a full domain and the scale was fully developed).
"s.e." = "standard error", "s.d." = standard deviation
Note for all tables
For all references to Argentina, Kazakhstan and Malaysia, the OECD consider that the coverage is too small to ensure comparability. See Annex A4 of Volume I of the OECD report for further details.
