Those numbers, if I'm not mistaken, are *percentages* of students scoring proficient or higher in each subject. Adding up percentages in this way, especially when they reflect different data points, is not all that meaningful as a comparison.<br /><br />For example, suppose you asked a group of people whether they liked apples, then asked the same group whether they liked oranges. 70% say they like apples and 60% say they like oranges. You wouldn't add those numbers together and say that "130% like apples and oranges."<br /><br />If you want to compare NECAP, it's probably best to compare each subject area separately, whether you're using percent proficient or some other data point like mean scaled score.FlyingSquirrelhttps://www.blogger.com/profile/04521082551731847722noreply@blogger.com
