The composite score is used to determine admission to a Specialized High School… The composite score is the sum of the ELA and mathematics scaled scores. The conversion from raw score to scaled score is done separately for each section (ELA and mathematics). The closer you are to getting every question in a section right (or every question wrong), the more your scaled score goes up (or down) for that section… At the top or bottom of the range of scores, an increase of one raw score point may correspond to 10–20 scaled score points. The raw scores and scaled scores are not proportional… For example, in the middle of the range of scores, an increase of one raw score point may correspond to an increase of three or four scaled score points. įirst, I assume the following statements by the DOE are true: Joshua Feinman is available at the following link. The rest of this post will go through the assumptions I make and the sources I use. I believe that after some adjustments, we can continue to use the study to convert raw scores into scaled scores for practice tests. Nevertheless, I still find the 2008 study to be the most comprehensive of its kind and still highly relevant. There are now 10 field questions in each section which they don’t count at all, and also 19 more questions (95 to 114). The exam changed in 2017 and then again in 2018. The 2008 study I mentioned above was able to suggest how people should convert raw scores into scaled scores. The exam also hadn’t gone through any changes in more than a decade and there was plenty of data available to figure out how they were being scored. The exam used to offer a total of 100 raw points split between the two sections. In 2016, and the previous years since 2008, calculating a scaled score was easy. Calculating a scaled score used to be easy Joshua Feinman and the DOE’s SHSAT handbook, the conversion rewards raw scores as they get closer to a perfect score. It can range from around 10-350 points for each section. The scaled score is converted from the raw score. Of the 47 questions that are counted in each section, every correct answer is worth 1 raw point and everything else, incorrect or blank, is worth 0 points. They don’t specify which questions are field questions, however. Of the 57 questions in each section, 10 of them are field questions that aren’t scored. They each have 57 questions for a total of 114 questions. The SHSAT has two main sections- the reading and the math. It doesn’t account for some of the more nuanced assumptions that I’ll cover below, but it is still handy. You can skip to the end of this post for a chart that lets you easily convert a raw score to a scaled score.
