The strand names the accommodation. A disability label tells you the rope; the map tells you the strand, and the strand tells you what to accommodate. For every strand there are two kinds of support: a bypass routes around the strand so the student can reach the content (most assistive technology lives here), and a scaffold supports the strand while it is being built. A bypass is an accommodation right up until the strand it bypasses is the thing being taught or measured; at that point it is a modification, and the last column says where that line sits for each strand. Supports that attach to processing speed, memory, or attention rather than to a strand are listed separately at the bottom so the ropes stay honest.
