The US School System: Grades, Ages and GPA Explained
There's no single high school exit exam in the US — instead, a GPA builds up over 4 years.
In short: US public school runs from Kindergarten through 12th grade (K-12): elementary (K–5, ages 5–11), middle school (6–8, ages 11–14), and high school (9–12, ages 14–18). There's no single make-or-break national exam like a "Thanaweya Amma" — instead, a cumulative GPA builds up over 4 years of high school, and report cards go out each semester or trimester. A child arriving from an Arab school system is usually placed by age first, then assessed for English and math support afterward.
What are the stages from kindergarten to high school?
Public school in the US is free from Kindergarten through 12th grade, commonly written as K-12. The school year usually starts in late August or September and ends in June, split into either two semesters or three trimesters depending on the district.
A child's birth date, not an entrance exam, determines which grade they start in. Every state sets a kindergarten "cutoff date," most commonly September 1, though it varies by state and can run as late as mid-October in some places.
| Stage | Grades | Typical age |
|---|---|---|
| Kindergarten | Entry year | 5–6 |
| Elementary School | 1st–5th | 6–11 |
| Middle School | 6th–8th | 11–14 |
| High School | 9th–12th | 14–18 |
Some districts group grades differently (for example a K-8 school followed directly by high school). The exact split is set locally by each school district, not by one federal law.
What high schoolers are actually called
The four high school grades have names you'll hear constantly, in school and in American movies: Freshman for 9th grade, Sophomore for 10th, Junior for 11th, and Senior for 12th — the graduating year.
How is GPA calculated?
There's no single "total out of 100" the way many Arab school systems work. Instead, US schools use a cumulative Grade Point Average (GPA) based on a 4.0 scale. Each subject's letter grade converts to a number, and the numbers are averaged across all classes.
| Letter grade | 4.0 scale value | Approx. percentage |
|---|---|---|
| A | 4.0 | 90–100 |
| B | 3.0 | 80–89 |
| C | 2.0 | 70–79 |
| D | 1.0 | 60–69 |
| F (fail) | 0.0 | Below 60 |
That's the "unweighted GPA." Many high schools also run a "weighted GPA" that adds an extra point (or half point) for Honors and Advanced Placement (AP) classes, pushing the scale up to 5.0. That's why a strong student's GPA sometimes appears above 4.0 on a transcript.
How individual grades are earned also varies by school: some weigh tests and projects heavily, others fold in class participation and homework. Ask each teacher how grading works at the start of the term.
What is a report card, and how do parents see it?
Every student gets a report card at the end of each grading period, showing a grade per subject and often notes on behavior and attendance. It isn't always mailed home — many schools post it to an online parent portal that a parent needs to register for at the start of the year.
What standardized tests does a student take?
Unlike a single national exam, US students face two different kinds of standardized testing:
- Annual state tests: measure reading and math roughly every year from 3rd through 8th grade, plus once in high school. Results are mainly used to evaluate the school, not to decide whether a student is promoted.
- College entrance tests: the SAT and ACT, optional or required depending on the college, usually taken in 11th or 12th grade when applying to college.
Some students also take Advanced Placement (AP) subject exams in their final high school years — optional tests that can earn early college credit if the score is high enough.
How many credits does a student need to graduate?
Students graduate high school through a credit system, not one final exam. Passing a full-year class usually earns one credit, a half-year class half a credit. The total number of credits required, and which subjects are mandatory, is set by each state and often by each school district — there's no single national number.
What most states share is a required number of years of English, math, science, and history/social studies, plus physical education, on top of electives the student picks themselves — a foreign language, art, or computer science, for example. Ask the school counselor for your specific state's graduation requirements right after enrolling, since this list shapes the student's entire four-year plan.
How is a student coming from an Arab school system placed in the right grade?
When registering, most schools place a child by age and birth date first, the same way they would for any American student. School records from Egypt, Jordan, Iraq, or any other Arab country are required for enrollment, but in most cases they aren't used to move a student up or down a grade — only in exceptional cases the district decides after review.
- Translate the school transcript: Bring at least the last two years of grades translated into English. Some schools accept an informal translation, others require a certified one.
- Don't expect an automatic GPA conversion: A US high school doesn't convert a foreign school's final score directly into a GPA — the student typically starts a fresh GPA from the grade they enter.
- Ask for an English-level assessment: A non-native English speaker is usually given a placement test and, if needed, enrolled in an English-language support program (ESL/ELL) alongside regular classes, not instead of them.
- Ask about matching years of schooling: If your home country's system counts pre-high-school years differently, explain that to the registrar so the student lands in the grade that best matches both age and academic background.

What about an older student arriving mid-high-school?
A student arriving at 16 or 17 faces a different challenge: the time left before graduation may not be enough to meet every credit requirement if prior coursework from their home country isn't recognized. This is where the school counselor's role becomes critical — ask specifically whether some Arab high school subjects can be counted toward US credits, and what the alternative is if not, such as extra summer classes or an alternative diploma track set by the district.
Anyone planning to continue on to college later, holding a diploma or degree earned abroad rather than from a US high school, will eventually need a separate step entirely called foreign credential evaluation — covered in the foreign credential evaluation guide.
Common mistakes at enrollment and during the school year
- Waiting for one big "final exam": there's no single national exam deciding a student's fate — assessment is continuous over 4 years through grades and credits.
- Ignoring the online parent portal: many parents discover a slipping grade far too late because no one activated the online tracking account.
- Comparing GPA to a percentage total directly: GPA is a fundamentally different grading system from the "total out of 100" many families are used to — don't compare the two numbers literally.
- Ignoring the credit plan from 9th grade on: some required subjects aren't offered every term, so delaying one class can push back graduation itself.
- Relying on a relative for translation: some registrar's offices require a certified translation of school records, not an informal one from a family member.
What to do next
Enroll your child first using the detailed enrollment guide, then request an early meeting with the school counselor to go over the credit plan and English support together. If your child is approaching college age, also start looking into financial aid through the financial aid for immigrant families guide well before the final year of high school.
Frequently asked questions
What grade will my child be placed in based on age?
Kindergarten is usually for a child turning 5 by a state-set cutoff date (often September 1), then one grade per age year after that. Ask the registrar for your state's exact date.
Does my child's Arab high school diploma convert directly to a US GPA?
No. The student typically starts a fresh GPA from the grade they enter in the US; the prior record is used for enrollment, not for calculating an instant GPA.
What's the difference between weighted and unweighted GPA?
Unweighted tops out at 4.0 and treats every class equally. Weighted adds a point or half-point for Honors and AP classes, so it can exceed 4.0.
Is the SAT or ACT mandatory for every student?
No, it's a college entrance test, not a high school graduation requirement, and some colleges no longer require it. Check with the specific colleges you're targeting.
How many credits does a student need to graduate high school?
There's no single national number; each state, and often each district, sets its own credit total and required subjects. Ask the school counselor for your state's list.
My child arrived in 10th grade — will they graduate on time?
It depends how many credits from prior schooling can be counted. Discuss this with the school counselor early, since some required classes aren't offered every term.
