For any number of reasons, let's say we don't feel the tracings obtained on a chart meet our standard, where we feel confident in making a call.

In your vast experience, how many charts would you run in an attempt to get three that are satisfactory ?

BTW did anyone see the news report about the 100 year old pedophile that was released from prison? He says that he is too old to change his ways. The local DA says he is still a threat.

Generally, if you can't get enough qualifiable criteria in four charts, you don't have proper set. I don't think any school teaches to test until you have three good charts.

It's about enough criteria to make a call. Beyond four charts (without a call) I think, you're just collecting noise...

Ever wonder why the TES seems to outperform other screening techniques?

One thing you'll notice about it is that it requires three interpretable presentations of each RQs. If you don't have three, then you run a fourth presentation of the RQs, and score only the first three interpretable presentation for each RQ.

The major difference between this strict requirement and our common procedures with other techniques is that other techniques do not prohibit scoring to a conclusion based on 2 or 1 presentation. Anther difference is that the 4th presentation is not scored, unless it is needed to get 3. Yet another difference is that there does not seem to be any procedure for useless attempts to get 3 interpretable presentations if you cannot get them in 4 charts (presentations).

It's not concrete, but it's consistent with what Sackett has said.

This is not at all surprising. If you want good results, then collect good data.

DACA teaches run 3 charts and if sufficient data is not present you can run up to 5 charts total.

Our agency says 3 initially and a 4th if sufficient data is not present to make a conclusive call.

I am not aware of anyone who teaches or allows "cherry picking". That is running multiple charts and picking 3 that suit you or defend your call.

To my knowledge everyone teaches if you run it and it's scoreable then you score the spot and add it to the totals.

I am aware that there are some examiners who run several charts and then choose 3 charts that provide the basis for their decision but in my opinion, that's cherry picking and would create an ethical problem.
