Understanding your Score Report

Thank you for choosing Biometric Edge! Your score report contains a lot of information. Here’s how to understand it.


A student’s score is based on the scoring metric for actual exams. No one can claim their scoring is exact, however, as scoring curves change from year to year. 90% correct on the reading section of the SAT can yield a different score in 2020 than it did in 2019. We believe that our scoring is as accurate as possible.


Level of Difficulty

Test questions are scaled from 1 (easiest) to 5 (hardest). To obtain these rankings, we use a modified version of Bloom’s Taxonomy of Difficulty and the percentage of students who have answered this question correctly.

General Knowledge – General

This score shows how a student performed on each general topic, such as math or reading. Keep in mind that standardized tests are much more difficult than school exams, and the percentages should not be equal. A 70% on a school exam means a student needs to improve considerably. A 70% on a standardized test can be a good score, depending on the test and the subject.

General Knowledge – Specific

This score shows how a student performed on specific topics within a section, such as verb tense, triangles or science reading comprehension. Sometimes, a test will contain only one or two questions of a specific topic, so a 0% or a 50% doesn’t necessarily mean a student is horrible on that topic. It’s best to go over the exam to see which questions caused the most trouble.

One term that is not self-explanatory is transference, which is a student’s ability to transfer their knowledge to new types of questions they most likely haven’t seen in school. An example follows:

A circle has a radius of 2/p feet. How far does the circle have to roll to make five full rotations?

  • 10 feet
  • 20 feet 
  • 10p feet
  • 20p feet

Most students have studied circles in school, but few have seen a question like this. To solve, students must be able to transfer their knowledge of circles to determine that a circle will roll its circumference in one full revolution. The answer to this question is (B).

Time Awareness

Time awareness is a combination of different factors: did the student finish the section? How much time did they spend on the first 80% of questions versus the last 20%. Did they spend more than 3 minutes on a question before they finished every other question?

Vertical Fluidity

Vertical fluidity measures how often students reread reading comprehension passages when answering questions. This is a crucial component of doing well on reading comprehension and one that many students just don’t do.

Test Equanimity

Test equanimity measures how students recover after struggling on a question. It also factors in recovery time after a pulse rate spikes (if it spikes).

Attention to Detail

Certain questions require students to read closely. Attention to detail measures a student’s performance on those questions. An example is below:

Find the smallest even number that satisfies the equation. Newark High School needs to hire photographers to take portraits of the senior class. Each photographer can take 15 portraits an hour and work for 5 hours straight. After 5 hours, they need a 1-hour break and can then work for 2 more hours. If there are 250 students in the senior class, how many photographers must they hire to finish taking all senior portraits in one day?

  1. 2
  2. 3
  3. 4
  4. 5

It’s very easy, by the time you finish your work on this question, to forget what it says in the first sentence. The smallest number that satisfies the equation is 3. The smallest even number is 4.


Certain questions require students to do a lot of work. Many students give up on these questions. Grit measures a student’s willingness to work through difficulty to find the right answer. An example is below:

The width of a rectangle is increased by 20 percent and its length is decreased by x percent. If these changes decreased the area of the rectangle by 16 percent, what is the value of x?

  • 12
  • 30
  • 32
  • 36

As you can see, this isn’t a question that can be answered quickly. Students must put in the work to find the correct answer, which is (B).

Overall Test Readiness

Overall test readiness (OTR) is a combination of different categories mixed with a student’s score and their performance on specific levels of difficulty. Understand that this is a general measure and may not coincide with your expectations or your child’s expectations. For example, your child may have a target score of 600 for the math on the SAT. Their score in relation to that number is more important in that case than their OTR score.

The target score that your child entered at the beginning of the exam factors heavily into this metric.

Video and Session

Video and Session are recordings of the test. In video, you see the test taker. In Session, you see the screen. This can be helpful if a student is curious about how they could have missed a particular question (this happens all the time in tutoring). It provides more information for how long students spend on a question.

As you can imagine, these files are very large and may take time to load.


This report shows your child’s pulse, eye dilation, blink rate and time per question

How to use it: look for changes and cross-reference it with the question asked. For instance, if pulse rate jumped at 3:15, see which question your child was working on at this time (scroll over the red or green rectangle at the bottom of the chart for this information). This is good to go over with your child.

Answer Key

This key shows which questions your child got right and wrong and includes video explanations for almost every question.

Eye Tracking

This report lets you see if your child is re-reading passages when answering questions on the reading comprehension section. Going back to re-read passages is crucial for doing well on the reading comprehension section, and a lot of students don’t do it.

In addition, without this information, it’s very hard to tell if a student is re-reading passages on an exam, because it can differ from what they do with their tutor.


This shows the time a student spent on each question and on each reading passage. In the last column, we list the average time for this question.

For this metric, we advise you to look for patterns. How does your child do on geometry questions as a whole versus the average? How much time do they take on reading passages versus the average? One problem or one passage could be the result of many factors, but patterns give a more accurate view.

Keep in mind that performance can fluctuate depending on how a student is feeling, what they ate before the exam and how they slept the night before. Be careful of reading too much into one test. This is why we suggest multiple exams to get a more accurate reading of what a student most needs to improve.

To your child’s success!
