<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;;color:#1f497d">And thanks for the clarification of the information..I had just read that in RMT and forgotten about it!<u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;;color:#1f497d"><u></u>†<u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;;color:#1f497d">I THOUGHT I should be using the S.E. of the ITEM at the location of the pass standard because most things I have read indicate reading the S.E. off the logit
 in the score table (20.3 in Winsteps) that corresponds with the cut score , but once you add and subtract that S.E. from the cut score measure you donít have a direct raw score comparison of the borderzone range.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;;color:#1f497d"><u></u>†<u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;;color:#1f497d">So this seems a very basic error , and logically I guess using the Person S.E. at the cut point measure is really telling you how much precision the test gives
 you about student ability at that level, yes? †††<u></u><u></u></span></p>
