Demystifying Shoulder Assembly Structural Scores

Linear Appraisal scores can be tough to analyze. Oftentimes, linear appraisal explanations only further mystify the situation. The reasons are simple, Linear Appraisers are not trained educators. They are trained evaluators. This is an important distinction.

There is another problem. Linear Appraisers are under strict time constraints. Rushed evaluations can result in validity errors (in case you haven't read my bio, I'm a retired educational researcher, data and validity are my grooves). One possible error is the halo effect, where the evaluation (negative or positive) of one of an individual's traits affects the evaluation of the other traits. This error is common in all forms of evaluation.
​
I see that less with seasoned appraisers. They may have a bone to pick (e.g., rumps), but that bone doesn't affect their evaluation of the goat's other traits. Over the years, owners usually figure out what any particular appraiser's personal bone (or soapbox) is, and mentally adjust for that when looking at the scores. It's not a big deal because it didn't bias the evaluation of the other traits. 

Moreover, a rushed appraisal, coupled with limited opportunities to record the interaction, typically results in an incomplete understanding of the basis for a particular score. I've been doing this for over a decade now and I still look at my scores and try to figure out why one animal got a "Good Plus" in Shoulder Assembly while another animal got a "Very Good."

In this article, I'm going to go back to the basics, the ADGA Scorecard. The goal of this article is to empower owners to independently evaluate their goats and to be able to tease out what aspects of the shoulder assembly may need improvement. To accomplish this, I'm going to use photos of goats from my own herd.
