Preparing students for college and for life.

Although we do not believe that education’s first purpose should be college preparation, we are grateful that our program excels in preparing students for college and life.


Our average graduate exceeds the Idaho averages on both the SAT and ACT.

Colleges historically look to the ACT (American College Test) and the SAT (Scholastic Aptitude Test) as a measure of how successful a student will be upon entering college.

We graduate more national merit scholars than any other high school in the state.*

national merit scholarsEach year, over 3.5 million high school students take the Preliminary SAT / National Merit Scholarship Qualifying Test in their sophomore or junior year. This test helps you prepare for the SAT while determining your eligibility for a National Merit Scholarship. Since 2007, we have graduated 12 National Merit Scholarship semi-finalists. On average, 8.6% of our students qualify as semifinalists.

Understanding testing and standards in Idaho




What does Ambrose do with The Common Core, ISAT testing, State standards, and accreditation?

Standards are created by the state to answer two simple questions:

“What should a student know, and what should he be able to do?”

The Common Core is the basis for answering this question in Idaho. An assessment of how well a school goes about teaching students is made by the school’s accrediting agency. Schools in the state of Idaho are now accredited by the national accreditor– AdvancED.

In Idaho, a Common Core standards test is administered to students. This test is called the ISAT—Idaho Standards Achievement Test. Students are tested and categorized as either meeting the proficiency level, exceeding the proficiency level, or under-performing. It simply answers one question: Does a student or a group of students achieve proficiency?

This measurement can be deceptive as it does not reflect the level of reasoning in core academic areas that are important in life and on college entrance exams.

Aptitude-based tests measure a student’s aptitude in areas like verbal reasoning, quantitative reasoning, and writing.



For this reason, The Ambrose School uses the Educational Record’s Bureau’s CTP-4 test. This test is used at about 2,000 of the nation’s most rigorous academic schools. “Average” within the ERB testing pool is much harder to achieve than on other standards tests. The CTP-4 closely echoes the SAT and ACT in what it measures.

Between 3rd and 10th grade, our students advance beyond some of the best schools in the country. The ERB Independent School average is made up of a select group of the best private preparatory schools in the U.S. and abroad. We take this test, in part, because it measures our students against tough competition.

Many of these independent prep schools accept students based on their academic gifting, which naturally results in higher scores. Unlike these schools, we do not admit based on academic ability (though we do have a readiness test). This indicates that our program is successful relative to some of the best schools in the world at developing students who can accelerate their potential.


We achieve these results with regular kids. Most of our graduates have been with our school since the grammar stage.


ACCS accredited_blue-300x225Our rigorous ACCS accreditation places us among the best schools in the U.S.

The Association of Classical Christian Schools (ACCS) has accredited the Ambrose School since 2006. Nationally, classical Christian schools consistently outscore other schools, both public and private, on standardized tests.


“The Ambrose School is poised to make a difference in the lives of Boise’s families and eventually the culture. The emphasis of academics flowing from a Biblical foundation promotes an atmosphere of serious dialogue among faculty and students. The school is a community of learners, committed to the gospel of Christ.”   Michael Johnson, ACCS Accreditation Committee


The greatest measure of our success is the caliber of our graduates. SATs and other academic measures fail to communicate the true character which results from classical Christian education done well. Our students graduate knowing their purpose (to glorify God) and possessing a deep perspective of God’s world with its history, its beauty, its ideas, its math, its science, and its people.
