SAT tutoring is usually a humbling job. I discovered some 20 years in the past that simply once I assume the check makers have made a mistake, I ought to assume once more. Given the assiduous scrutiny every check merchandise receives earlier than it turns into operational after which scored, skilled SAT tutors who run right into a perplexing answer have been sensible to first ask themselves, “What am I lacking?”
That each one modified this month.
Right here is the story of how a Compass tutor and his scholar found a test-maker error on the SAT, how we acquired it corrected, and what this implies for all college students.
Might 4th, 2019
About 400,000 college students awoke early Saturday morning to take the SAT, an 8am begin at a School Board designated check website hopefully not too removed from house. Armed with image IDs, check registration tickets, an authorised calculator, a few pencils, a silent timer maybe, and perhaps a light-weight snack, every scholar obtained checked in and assigned to a room. They might spend the subsequent 45 anxious minutes “spelling out” their private info, one tedious bubble at a time, earlier than seeing even the primary check query. They have been in for an extended day.
As soon as the precise examination started, college students confronted 65 minutes value of dense studying passages and 52 corresponding questions. Then they took a brief break. The subsequent part, 35 minutes lengthy, included 44 extra questions that required college students to rigorously proofread textual content for errors. Nevertheless one carried out throughout these 100 fateful minutes can be transformed right into a scaled rating between 200-800, out there on-line a number of weeks later. Sure, one-half of their SAT rating that might sometime quickly issue into school admissions selections was now successfully within the books, a part of one’s official testing transcript.
However now was not the time to consider that; there was nonetheless a math portion to endure. College students have been allowed one other 25 minutes to finish the subsequent 20 questions but in addition advised to place their calculators away for this primary math part. And because the minutes ticked by, the questions received more durable; the maths sections are organized that means. Lastly, after another very brief break, college students launched into the final obligatory portion of the SAT: a 55-minute, 38-question math part that allowed calculator use.
And identical to the prior math part, these questions received steadily more durable alongside the best way. The 2 sections had one thing else in widespread, too: they switched from a multiple-choice format to free-response for the ultimate handful of issues (questions 16-20 within the first part; questions 31-38 within the latter). College students have been to reach on the right reply on their very own after which “grid-in” the worth. And that’s the place issues acquired fascinating.
As a result of close to the top of the third hour — in all probability very near midday typically — check takers encountered a query (the now notorious “Might 2019 SAT, Math w/Calculator #35: Median” query) that might make historical past! Nicely. Or a minimum of an excellent story a few tutor and a scholar elevating about 50,000 SAT scores. I’m attending to that.
The query seems under. Attempt it your self, however first attempt to put your self within the footwear of an official check taker. It was not solely one of many final questions of an exhausting math part, it was the 151st query of an interminably lengthy 154-question marathon. It was not merely a considerably troublesome drawback in isolation, it was additionally positioned in order that many college students have been mentally taxed, hungry, too scorching, too chilly, brief on time, or all the above when trying to unravel it.
Astute readers might have observed a slip in one thing I wrote a second in the past. I did that on function. I stated that on free-response questions college students are to reach on the right reply on their very own. However in contrast to a number of selection issues, free response questions typically permit for a variety or collection of right solutions, so college students should solely present *a* right reply. Correspondingly, the check makers should then account for each attainable right reply when scoring the check. And that’s the place the error was made.
Most college students perceive that the median is the center worth when all the values are sorted. The histogram signifies that college students can’t know the precise quantity, however they will nonetheless discover the center. Virtually. When there’s an odd variety of values, one in every of them will probably be within the center. Fewer college students know the rule that, with a good variety of gadgets, the 2 center values have to be averaged to seek out the median. Within the query above, we would like the typical of the 25th and 26th record gadgets. These must be within the third bar, because the first three have 12, 9, and 9 gadgets. The third bar has integers higher than or equal to 10 however lower than 15 (i.e., 10, 11, 12, 13, 14). These might individually be any mixture of numbers inside this vary. Since we’ll be averaging two, we might get any of those values and any of the half values between them. That is the place the builders took a flawed flip. They assumed that the 2 center values can be the identical. However the 25th and 26th values didn’t should be similar. That’s, the 25th and 26th gadgets might be any of the pairs 10/10, 10/11, 10/12, 10/13, 10/14, 11/11, 11/12, 11/13, 11/14, 12/12, 12/13, 12/14, 13/13, 13/14, 14/14. These end in median values of 10, 10.5, 11, 11.5, 12, 12.5, 13, 13.5, 14.
Might 17th, 2019
Might SAT scores, as promised, have been posted on-line. A whole lot of hundreds of check takers logged in to their School Board accounts to see their official SAT scores displayed in giant numerical font on display. Many presumably stopped there, though they might’ve double-clicked into the detailed sections of the report back to see precisely how they earned a given scaled rating. As a result of the Might check is launched publicly to all check takers (that is associated to School Board adhering to Fact-in-Testing legal guidelines courting again to 1979 that stipulate sure transparency necessities), college students got the choice to entry (for an additional $18) the entire Query-and-Reply (QAS) report. The entire check – the questions and the suitable solutions – have been now obtainable to the general public.
And on this report, the School Board initially acknowledged solely integer values (10, 11, 12, 13, 14) as right solutions to the query above. A solution like, say, 12.5, was marked fallacious.
Might 18th, 2019
Saturdays are widespread tutoring days at Compass and today was no totally different. We carried out lots of of personal periods that day throughout the nation however one in San Francisco is notable as a result of it was when this error was first correctly disputed. One in every of our math tutors was assembly with certainly one of his college students they usually spent a while reviewing the scholar’s Might SAT QAS report. That is widespread follow — brazenly inspired by the School Board the truth is — as a method to consider one’s personal work and study from actual issues as case research.
Once they received to the above query, this whip-smart tutor (a former ACT challenge supervisor, no much less) had that sinking feeling we’ve all had as tutors: “What am I lacking?” I just lately re-read the string of emails that ensued, and he requested that very query. After ending the lesson, the tutor reached out to the top of our Math division in Northern California and wrote:
. . .The suitable solutions are all integers, however there are 50 gadgets within the set, so the median can be the typical of things 25 and 26, which might be 12 and 13, so I’m unsure why [my student’s] reply of 12.5 isn’t acceptable. What am I lacking? It’s in all probability one thing apparent, however I can’t determine it out.
(The “test-is-never-wrong” default mindset was in full drive right here.)
Might 20th, 2019
Our Math Lead learn this on Monday morning and first thought she wanted a second sip of espresso. “What the heck am I lacking?” She checked her sanity with a senior member of her math coaching staff and he agreed she wasn’t dropping her thoughts. The check maker, gasp, might have tousled?
In the meantime, I used to be operating from my aircraft to an Uber in Phoenix on my approach to an annual school convention once I was made conscious of what was found. Skimming the abstract on my telephone, I initially surmised there have to be some qualifying (or disqualifying) element embedded within the query that restricted the suitable solutions to these offered on the reply key. There was no different rationalization I might settle for. It appeared like the best choice of my very own psychological a number of selection:
a) Hadn’t this query been completely vetted?
b) Hadn’t this query already been used with out incident on prior exams?
c) Aren’t obvious errors flagged earlier than scores are despatched to college students and schools?
d) We have to be lacking one thing!✔
However once I acquired to my lodge room that night time, I checked out it once more. And once more. And once more. And eventually, I figured, I’ll ask. I sheepishly reached out to the suitable man on the School Board who I knew would resolve it. I absolutely anticipated a reply that was going to embarrass me for overlooking one thing apparent. I heard again the subsequent day . . .
Might 21st, 2019
. . . And . . . he agreed with all of us. 12.5 positive looks like it could possibly be right. He would look into it with the evaluation design workforce and get again to me.
Might 23rd, 2019
I acquired an replace that the School Board was engaged on resolving this error shortly. My contact expressed honest appreciation for flagging this error. School Board was proudly owning it and would presumably challenge corrected scores and a press release quickly.
Might 30th, 2019
After every week of not listening to something about this from anybody at School Board or elsewhere, I checked again in with my contact there. He stated the decision had simply been finalized this present day: an e mail would exit with up to date scores within the subsequent 1-2 enterprise days. Not each scholar who was impacted would get an up to date rating as a result of in some instances a further uncooked rating level doesn’t change the scaled rating. In different instances, the scaled rating will rise by 10 factors. On different check types, one uncooked rating level can translate to 20-30 scaled factors in some situations.
(We encourage readers to submit their rating updates in our Feedback part.)
My contact signed off by saying, “thanks once more on your assist right here; it’s actually appreciated by everybody.” He then shared a draft of the notification that may exit to affected college students; it was simple:
Your Might SAT® Math rating has elevated barely as a consequence of a correction on the reply key that was used to attain the check. For one math query you answered appropriately, the unique reply key didn’t embrace all the right solutions. We have now recalculated your rating, and you may entry it on-line now. Should you despatched your scores to a school or different group, they’ll obtain the up to date scores early subsequent week. Please attain out to us with any questions at 866-756-7346.

Nationwide Media Protection and Broader Penalties
Quickly, the media picked up on the story. Inside Larger Ed and Newsweek have been among the many first to cowl it. (true story: A reader from the UK referred to as Compass after seeing the Newsweek article and requested if the eagle-eyed tutor might work together with her daughter. Positive!) These articles additionally touched on some fascinating questions. I’ll take a look at 4 huge ones right here:
What number of college students have been affected on this check?
School Board hasn’t disclosed that determine so we will solely make an knowledgeable guess. We expect it’s larger than eight,000 (2%) and fewer than 80,000 (20%), in all probability between 25,000-50,000 college students. Whereas this specific drawback doesn’t strike me as one of many hardest of the arduous, the idea of histograms is overseas to some college students. The situation of the issue towards the very finish of the part and the check suggests it was a query that has stumped most college students. Maybe as many as 75% of all test-takers, or about 300,000. I think the overwhelming majority of those that obtained it improper did so for different causes: they left it clean, they guessed, or they “eyeballed” the median someplace nearer to the center bar. If we estimate that solely about 15-20% of the “improper” solutions have been certainly right, assuming just one in four obtained it proper within the first place, that’s about 50,000 college students. That could be a bit excessive, nevertheless it could possibly be just a little low. Solely the School Board is aware of for positive.
What number of college students have been affected by this query on a earlier check?
I don’t see how we’ll ever know. However until and till School Board affirmatively denies that this query ever appeared as an operational merchandise on a earlier check, the affordable assumption is that it did. As soon as a sure model of a check is made obtainable to the general public it should by no means be used once more. However earlier than that occurs, it’s used on check dates that don’t get launched to the general public. Some variety of SAT takers previous to Might 2019 virtually definitely encountered this query and acquired scores that didn’t account for this error.
Do 10 factors actually matter?
We’d wish to assume not, however in some instances it’d. And, for some college students this query might have been value 20 factors, relying on the place they have been on the size. Whereas school admissions officers usually understand (or no less than they *ought to*) that the check isn’t designed to make significant distinctions between SAT scores 10 factors aside, there are certainly particular situations the place actual scores matter. Incomes NCAA eligibility and qualifying for sure scholarships are two examples. There are sadly different anecdotal instances the place school officers (admission reps, athletic recruiters) casually speak in overly exact methods about the necessity to attain a sure rating.
Has this ever occurred earlier than?
Nicely, which half. Sure, errors occur on exams. On costly, excessive stakes standardized checks constructed by skilled psychometricians, they don’t occur all too typically. Questions on the SAT and ACT undergo rounds of improvement, assessment, and pre-testing earlier than they grow to be operational. And if a problematic query makes it that far, it’s virtually all the time caught within the weeks between administration and the discharge of scores, after which thrown out.
School Board used to contract with a separate entity, Instructional Testing Service (ETS) to develop the SAT and handle high quality management. Beneath ETS, only a few errors have been made. Since School Board President David Coleman took again management of the SAT, there was a well-documented slip in high quality requirements. On the PSAT, for instance, which is launched yearly, errors have appeared with extra regularity.
As for a flat-out error being found by a member of most of the people, this can be a first for Compass. This expertise jogged my memory of an identical story from 22 years in the past when Colin Rizzio, a scholar in New Hampshire, challenged the reply to an SAT Math query and was discovered to be right.
To underscore how huge a deal it was at the moment, Colin was coated in a New York Occasions article, appeared on Good Morning America, and had the offending SAT query named for him!
That story is a superb learn to point out how issues have modified since then too. Beginning with the truth that Colin’s problem went unread for a lot of months because of the avenue he took to submit it: e-mail.
As a School Board spokesperson defined on the time, ”We’re fairly used to getting inquiries from check takers at a submit workplace mail handle. This was the primary time a check taker had despatched a query via the Web and it one way or the other simply received picked up by our common customer support division.”
Now, who can we write to about getting an SAT query named for somebody?
