Are Shorter SAT Reading Passages Easier? Research Says No

When the SAT moved to an all-digital format in 2024, it started using shorter reading passages in the Reading and Writing section. But the shorter passages don’t make the test any less challenging or buoy students' scores, as research involving nearly 200,000 students confirms.  

One study found that students who took both the previous paper and pencil SAT (with longer passages) and the digital SAT (with shorter passages) scored consistently across the formats. A separate, controlled study found that, on a test with both short and long versions of the same reading passages, students performed the same or even better on questions tied to the longer passages.   

These studies add to a significant body of evidence showing that the shorter passages retain the rigor and measurement value of the longer passages used on previous versions of the SAT. They also suggest that periodic claims in the media that the SAT literacy section is less challenging are not grounded in data or evidence.    

Why Did the SAT Switch to Shorter Passages?  

The SAT switched to shorter reading passages in its Reading and Writing section to facilitate digital adaptive testing, which allows for more precise and efficient measurement of students’ knowledge and skills. Use of the shorter passages also broadens the range of texts and topics covered on the test and allows students to read closely and engage with the content rather than hurriedly skimming for keywords in longer passages. 

At the time of the transition to digital, College Board published extensive documentation showing that the redesigned Reading and Writing questions tested the same knowledge and skills as previous test versions and were equivalent in difficulty level.    

But this hasn’t stopped repeated circulation of the claim that the shorter passages must mean an easier test. It’s an intuitive, easy-to-understand argument. The change in passage length was one of the most visible changes to the SAT, and passage length feels like a proxy for difficulty.  

But presumption is not evidence. 

What Does the Research Say? 

The new research, published by College Board in July 2026, directly addresses the question of whether the shorter passages are easier. It comprises two carefully crafted studies using different methodologies and involving nearly 200,000 students.  

Study 1: Direct Comparison Across Formats 

Researchers examined the performance of 90,000 students who, during the transition period, took both the paper and pencil SAT (with the longer reading passages) in 2023 and the digital SAT (shorter reading passages) in 2024.  

Result: Students scored consistently across the test formats on the Reading and Writing section, with a very high correlation of 0.87. In other words, the change in reading passage lengths didn’t make much of a difference in their scores.  

For comparison, the researchers also looked at a different group of 100,000 students who retook the paper and pencil SAT with no format change. Their scoring pattern was virtually identical, with a 0.89 correlation. This shows that the passage length change added no more variability than normal retesting does.  

These scoring similarities were consistent across student literacy achievement levels.  

Study 2: Controlled Experiment with Long and Short Passages 

Researchers recruited 367 students to take simulated SAT modules that included an equal number of both short and long versions of the same reading passages in four subject areas. Question skill and difficulty were held constant.

Result: On average, students performed better or similarly on the questions tied to the longer passages—directly contradicting the assumption that shorter passages must be easier.  

That scoring trend was the same whether students had low, medium, or high prior literacy achievement. It also held across questions in history/social studies, the humanities, and science. In literature, students did slightly better on shorter passages (by 0.1 on a 2-point scale)—but the effect size (or practical impact) of this difference was small and driven entirely by a subset of students with low prior literacy achievement. 

What Are the Key Takeaways From this Research?  

Together, these studies:  

• Provide additional empirical evidence that the shortened reading passages on the SAT don’t make the test less challenging or meaningfully affect student scores.  
• Add to a substantial body of research supporting the validity and rigor of the Digital SAT and showing it continues to assess the complex literacy skills students need for college and career success.   
• Suggest that what makes a reading question hard is the complexity of the text and how the question is written, not how long the passage is.
