Coincidentally, I had a parent&#x2F;teacher conference with my 1st grader&#x27;s teacher yesterday afternoon.  Regarding reading level &amp; comprehension, she remarked that current research indicates anything below about 98% comprehension isn&#x27;t sufficient for reading &quot;fluency&quot;.  Before the past few years, the standard was 95% comprehension = fluency, but that extra few percentage points apparently make an enormous difference (probably because of colloquial &amp; jargon edge case usages that carry specific meanings in specific contexts, but which aren&#x27;t easy to programmatically detect, but that&#x27;s just my supposition).
