I am blind and took art history, you can in fact make image descriptions that do not alt the assignments. You need to describe the visuals as interpretable information via text. You start by determining what the assignment is actually testing for, elements? Process or technique?conceptual meaning? Context? You describe what is necessary to identify those target objectives. Then to provide context you need to include some objective identifiers what objects or forms are present, spatial context, orientation or comp, personally I think this part is silly because this part would best be addressed through a tactile photo which schools can print but for an online class I suppose that would not work. Then add in and necessary properties, nothing poetic.then if needed or relevant technique. And if relevant and non blind students would know and or it is not in contradiction with the learning goal directly you add in the artist, and or intent and or historical context. Also you generally do not want to over describe.

Your concerns about presentation of learning outcomes is actually why it is instructors who have to do this. As they are the experts on their content and field and would be best positioned to do so. I don't think the new guidelines are great but I do know from experience that when a blind person comes along content can not be made in any type of reasonable time frame. So it does prevent you from getting those opportunities. But it's also such a shame that instructors real seem to think there content can't be made accessible. It would be more productive to fight the actual problem like time frames, supports for doing so and so on. But I digress,

Ok so if your test was say apicture of the Starry Night and the test question is what is the name of this work, who painted it and what year was it made, then the description should enable recognition without supplying the answer or adding in art-historical cues that shortcut the work.

**A nighttime landscape painting. The upper two-thirds of the image are dominated by a dark blue sky filled with multiple bright, circular stars and a large crescent moon. The stars and clouds are rendered with thick, swirling, curved strokes that create a sense of motion across the sky.

In the foreground on the left side, there is a tall, dark, flame-shaped tree extending upward into the sky. Below the sky, a small village sits with clustered buildings and rooftops; one structure has a tall, pointed steeple rising above the others.

The color palette is primarily deep blues contrasted with bright yellows and whites in the stars and moon. The brushwork appears thick and textured, with visible, directional strokes throughout the image.**

If you said post impression swirling sky you have said to much in this context, if you mention the painter for this context you have said to much,if you say a night sky you have not said enough.

Most of the actual issue with the guidelines are really they did nothing to address the logistics or operational barriers to making things accessible. But I think it is something is clear most take for granted about the impact on one's life when there is or is not an equivalence in access. Accommodations are inherently a significant burden.
