<p class=MsoNormal>Apologies not sure of correct email for posting to Rasch
forum. Trying to send below message.<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal><span style='color:#1F497D'>Dear All, <o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'><o:p>&nbsp;</o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>I have a similar problem, and
the group anchor doesn&#8217;t seem to have resolved the subset issue, so I am
wondering if there is something else I can do or how I need to interpret the
analysis. <o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'><o:p>&nbsp;</o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>I have applicants taking an oral
exam consisting of 9 seven minute questions . The questions are very structured
from the examiner point of view and examiners are trained. <o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'><o:p>&nbsp;</o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>Because there are a large number
of applicants being examined over a number of weeks, different subsets of
questions are used in &#8216;circuits&#8217;. <o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'><o:p>&nbsp;</o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>The subsets of questions are
partially crossed, ie one question is in all circuits and many are in more than
one. (there are about 50 questions across 13 circuits). Applicants are
obviously completely nested within circuits but examiners are partially crossed
with circuits (and questions) because many examiners examine on more than one
day. <o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'><o:p>&nbsp;</o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>I ran the Facets model with
examiner, applicant, qn (item) , and question circuit as facets. Applicants and
circuits were in up to 21 subsets. I group anchored the circuits because we do
assume they are of equal mean difficulty (to be fair) and we certainly
don&#8217;t assume applicants to be of equal ability (they are ranked on their
scores). <o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'><o:p>&nbsp;</o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>I still have 11 or so subsets,
and I can&#8217;t group anchor the applicants obviously. Is there anything else
I can do or is it a case of we must have more crossing of items across
circuits? When I run the analysis without the &#8216;circuit&#8217; facet there
is no subset problem, but I&#8217;m not sure how useful this analysis in
determining &#8216;fairness&#8217; of the experience across applicants. <o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'><o:p>&nbsp;</o:p></span></p>
