Data Overview

Alexander Academy is the only test prep company in Atlanta that publicly posts all of its results every semester. Please take a minute to check out our students’ scores from our last three semesters.  


SAT

Below is the score data for our 2015/2016 students.  These charts display average score increases of over 262 points for students who completed most assignments (the majority of our students) across the three sections of the SAT.  In 2012, the New York Times estimated that increments of 80-100 points can make a difference in college applications.

This chart shows students’ “Before and After” SAT scores.  The starting scores (previous official SAT scores where available, or else PSAT or practice SAT scores) are shown in blue, and their final SAT scores are shown in red.

This chart shows each student’s improvement in a blue vertical bar. The bottom of the bar shows the student’s “before” score, and the top of the bar shows the “after” score.

For the next two charts, we have separated students’ scores according to homework completion.  The graphs show a correlation between the amount of homework completed and the amount of improvement on the test overall.

Part of this is likely a selection bias – the type of student who diligently completes all the homework is probably the type of student who is most focused and dedicated in all areas of the class!  Still, we strongly believe in the value of carefully crafted weekly assignments, and are happy to see that it makes a difference.

Students who completed more than 85% of the homework saw an average improvement of 263 points on their composite score.  Students who completed more than half of their weekly homework assignments saw an average boost of 209 points.  Students who completed the class, but did less than 50% of the assigned homework, saw average improvements of 156 points.

 

ACT

Below is the score data for our 2015/2016 students.  These charts show an average improvement of over 3.8 points for students who completed most assignments (the majority of our students) on our students’ composite ACT scores.

This chart shows students’ “before and after” ACT scores.  The starting scores (previous official ACT scores where available, or else practice ACT scores) are shown in blue, and their final ACT scores are shown in red.

This chart shows each student’s improvement in a  blue vertical bar.The bottom of the bar shows the student’s “before” score, and the top of the bar shows the “after” score.
