Inapplicable values in qfhigh_dv variable
Dear support team,
I am confused when examining the derived variable "w_qfhigh_dv" for respondents' educational qualifications. I found that even though it is a derived variable, namely it incorporates all respondents' answers, and the question is a universal question that asked to all, why is there still a large number of -8s (inapplicable)?
Thank you very much for your help in advance.

Please check the variable note for qfhigh_dv (https://www.understandingsociety.ac.uk/documentation/mainstage/dataset-documentation/variable/qfhigh_dv): "Note that not all respondents were ever asked the highest educational qualification question (QFHIGH); the group is mainly comprised of BHPS respondents and Rising 16's who had a youth interview in Wave 1 and were incorrectly routed out of the initial conditions module in Wave 2. From Wave 6 onwards it also includes members of the IEMB sample who provided an adult interview and reported that their highest qualification was obtained abroad (see F_QFHIGHOTH and F_ISCED11_DV). Highest educational qualifications may be picked up through QUALNEW or TRQUAL for these groups but may be additional to pre-existing (potentially higher) unobserved qualifications. The variable QFHIGHFL_DV flags whether a respondent has ever been asked the initial conditions highest qualification question (QFHIGH)."
