A private school course catalog can be impressive. Advanced mathematics, multiple world languages, specialized sciences, computer science, studio art, economics, psychology, engineering, and advanced literature may fill dozens of pages. But there is an important question families sometimes overlook: Are those classes actually offered every year?
The distinction matters. A catalog usually describes the curriculum a school is capable of offering. It does not necessarily guarantee that every listed course will appear on next year's schedule.
For families comparing schools, the course availability test means moving beyond the catalog and examining what students can realistically take. Enrollment, teacher availability, scheduling conflicts, prerequisites, and student demand can all affect whether a course runs.
Understanding that difference can prevent disappointment after enrollment and provide a clearer picture of a school's academic depth.
Why the Course Catalog Does Not Tell the Whole Story
Private schools have considerable flexibility in designing their academic programs. That flexibility can produce distinctive electives and advanced courses, but it also means families need to investigate how the curriculum works from year to year.
A catalog may include courses that are offered annually, every other year, only when enough students request them, or through independent study. Some courses may be temporarily unavailable because a teacher is on leave or because the school has changed staffing.
This does not necessarily indicate a problem. Smaller schools, in particular, may use rotating electives to provide students with a wider curriculum over four years than they could sustain simultaneously.
The key is transparency.
Families beginning their search can use Private School Review's Checklist for Comparing Schools to organize questions about curriculum, faculty, facilities, and other characteristics. Course availability deserves a place on that checklist.
The Course Availability Test: Compare the Catalog With the Schedule
One of the simplest ways to evaluate academic offerings is to request two documents: the current course catalog and the actual master schedule or course list for the current academic year.
Then compare them.
Suppose a high school catalog lists 14 advanced or specialized electives. If only six are running this year, ask what happened to the other eight. Some may alternate annually. Others may have been canceled because enrollment was too low. A few may not have run for several years.
Ask admissions or the academic office which courses are guaranteed to run each year, which depend on minimum enrollment, which rotate every other year, which listed courses did not run this year, and how often students cannot enroll in requested courses.
Those questions provide considerably more information than simply asking, "Do you offer computer science?"
Private School Review's guide to evaluating and choosing a private school provides additional considerations for looking closely at a school's programs rather than relying on general impressions.
Look at Three Years, Not Just One
A single year's schedule can be misleading. A teacher may be on sabbatical. An unusually small class may affect demand for an elective. A new program may still be developing.
Ask for course offerings from the previous two or three academic years.
Patterns quickly become visible. A course appearing every year is probably a dependable part of the curriculum. One appearing every other year may be intentionally rotated. A class that remains in the catalog but has not appeared on a schedule for three years deserves further explanation.
This historical approach is particularly important when a course is central to your child's interests.
A student hoping to study Latin through an advanced level, for example, needs more than confirmation that "Latin is offered." The family should determine whether the full sequence operates consistently and whether enough students typically continue to the upper levels.
Verify AP Courses Separately
Advanced Placement offerings deserve additional scrutiny because families have an outside resource they can consult.
The College Board provides information about the AP Course Audit, the process through which schools receive authorization to use the AP designation for courses. Families investigating an advertised AP program can compare a school's information with College Board resources.
There is still an important distinction between an authorized course and student access. A course can be part of a school's academic program while scheduling, prerequisites, staffing, or enrollment policies affect which students can take it in a particular year.
Ask how many sections actually run, how students qualify, and whether scheduling conflicts routinely prevent students from taking particular AP combinations.
Ask the Same Questions About IB Programs
Families considering International Baccalaureate programs should also distinguish between the broad IB curriculum and the subjects available at an individual school.
The International Baccalaureate provides information about Diploma Programme courses and how subjects fit within the wider IB framework. The range of IB subjects generally available should not be confused with the specific courses an individual private school schedules.
Families should request the school's current IB subject list, including Higher Level and Standard Level options where applicable.
Ask whether subjects are taught every year, whether some are combined into small classes, and what happens when only a few students request a particular subject.
School Size Can Shape the Answer
Course availability often reflects the realities of school size.
The National Center for Education Statistics publishes Private School Universe Survey data covering characteristics of U.S. private schools, including enrollment and staffing. Those differences provide useful context when families consider how much curriculum a particular school can sustain.
A large private high school may have enough students to support several sections of calculus, multiple languages, specialized arts courses, and narrowly focused electives simultaneously.
A smaller school may offer challenging academics but organize them differently. It might alternate economics and psychology, rotate advanced arts courses, combine upper-level language students, or arrange independent studies for specialized interests.
Neither structure should automatically be considered stronger. What matters is whether the structure works for your child.
Private School Review's discussion of student-teacher ratios in private schools provides another example of why headline numbers require interpretation. The same principle applies to course counts. A large number in a catalog means little unless students can access those classes.
Watch for Scheduling Conflicts
A course can technically be "offered" and still be difficult to take.
Imagine that orchestra, AP Chemistry, and advanced French all meet during the same period. A student interested in all three has access to each course individually, but not to all three.
This is why families with strong academic or extracurricular interests should ask about common scheduling conflicts.
Can advanced STEM students continue orchestra? Can athletes take laboratory courses without recurring conflicts? Can students combine two advanced languages? Are required religious studies or other mission-based courses built into the schedule in ways that reduce elective space?
These are practical questions, not minor administrative details. A school's scheduling structure determines how much of its catalog any individual student can actually experience.
Ask Students What Really Happens
Admissions officers can explain curriculum policy. Current students can often explain how that policy works in practice.
During a campus visit, ask students which electives filled quickly, which courses were canceled, and whether they generally received their first-choice classes.
Private School Review's article on what to ask current parents provides another way to investigate the everyday experience behind admissions materials.
Parents of older students can be particularly useful sources. Ask whether their children have encountered canceled electives, scheduling conflicts, or difficulty progressing through advertised academic sequences.
The purpose is not to catch a school making a mistake. Course schedules inevitably change. You are trying to understand how predictable the academic program is and how clearly the school communicates those changes.
Pay Attention to Teacher Continuity
Some specialized courses depend heavily on one faculty member.
If one teacher handles physics, advanced physics, robotics, and engineering, ask what happens to those offerings if that person leaves. Similarly, a language program with only one instructor may have less scheduling flexibility than a department with several teachers.
Faculty turnover does not automatically mean courses will disappear. Schools may hire replacements or redesign programs. Still, when your child's academic plans depend on a specialized sequence, understanding staffing depth is worthwhile.
This is particularly important for courses students expect to take several years in the future. A sixth-grade family evaluating a K-12 school should not only examine what current sixth graders study. Look ahead to grades 9 through 12 and ask how consistently upper-level courses have operated.
Distinguish a Curriculum From a Promise
A private school should be able to explain the difference between its full curriculum and its annual schedule.
You may hear descriptions such as "offered based on student interest," "typically offered in alternate years," or "available through independent study." Those answers are useful because they reveal how the program actually operates.
Families should ask additional questions when nobody can explain when a prominently advertised course last ran or what determines whether it will run again.
Parents already devote substantial attention to tuition, admissions, class size, college counseling, facilities, and school culture. Academic availability belongs in that same due-diligence process.
The Bottom Line
The course availability test is straightforward: Do not count a class simply because it appears in the catalog. Determine whether it runs regularly, who can enroll, how many sections are available, and whether scheduling makes it realistically accessible.
For a student with broad interests, occasional rotating electives may be perfectly acceptable. For a student whose educational goals depend on advanced physics, Mandarin, computer science, ceramics, or a particular AP or IB sequence, consistency may matter much more.
The best question is therefore not, "How many courses does this school offer?"
Ask instead, "Which of these courses could my child realistically take?"
That small change in wording can turn a glossy course catalog into something much more useful: evidence of what the student's education may actually look like.
