Standard Elementary Grades by Age

Kids running to elementary school

In the United States, educators typically break schools down into three levels to cover kindergarten through senior year (12th grade):

  • Elementary
  • Middle School (Jr. High in some districts)
  • High School

Let’s start with elementary school. This is where your child will begin formal education and learn the basics of reading, writing, and arithmetic.

Elementary schools usually contain kindergarten classes and grades 1st through 5th or 6th, depending on the district. But how do those grade levels correspond to student age?
Let’s look a little further.

What Grade Are 5-Year-Olds?

Five-year-olds enrolled in kindergarten are at the beginning of their academic journey. Students typically turn six during the school year, though there are some exceptions, which we’ll discuss later.

In kindergarten, your child will learn basic, early-learning concepts like colors, shapes, letters, and numbers. They’ll also begin to develop social skills and independence.

What Grade Are 6-Year-Olds?

After completing kindergarten, your child will move on to first grade. They’ll typically be six years old for part of this school year.

The first-grade curriculum builds upon the fundamentals learned in kindergarten. Your child will continue to develop their reading and writing skills and become more fluent at addition and subtraction.

What Grade Are 7-Year-Olds?

Your child will likely be in second grade at seven years of age. By this point, they may have a solid understanding of essential reading and math concepts and be able to write longer sentences independently.

Second graders are often curious about the world around them and ready to explore science and social studies topics more deeply. They’re the perfect age for a Little Passports: World Adventures subscription!

What Grade Are 8-Year-Olds?

By the time they’re eight, your child will probably be in third grade — and halfway through elementary school. In addition to working on their academic skills, they’ll work hard on problem-solving and critical thinking.

Third grade is also the year when students stop learning how to read and start reading to learn. This is a crucial turning point in their education, as they’ll use their foundational reading skills to tackle more complex subjects in the future.

What Grade Are 9-Year-Olds?

Your child may be in fourth grade at nine years old. More complex math topics like fractions, decimals, and basic geometric principles will challenge their cognitive skills this year.

They’ll also work hard on their grammar and vocabulary, helping them become better readers and writers. Science experiments, social studies projects, and more complex homework assignments will also become a regular part of their routine.

What Grade Are 10-Year-Olds?

Once your child is 10, they’ll likely be in the fifth grade. During this final year of elementary school, your child will continue to work on advanced math skills like long division and tackle more complex writing assignments.

They’ll also face changing social dynamics as they gear up for middle school.

Standard Middle School Grades by Age

what grade are 13 year olds - 13 year olds in middle school

Welcome to middle school! In much of the United States, middle school encompasses grades six through eight, with students typically aged 11 to 14.

However, this is not a nationwide standard. Your district may have a slightly different setup, such as a junior high school model — with only 7th and 8th grades. In this case, your 6th grader would stay in elementary school for one more year.

Let’s look at how old children are in each of these grades.

What Grade Are 11-Year-Olds?

Your child will most likely be in 6th grade at 11. It’s an important transition year as they adjust to a new school and new expectations. They may be switching classes for the first time or dealing with more peer pressure and an increased workload.

What Grade Are 12-Year-Olds?

Twelve-year-olds tend to be in 7th grade, a year of academic and social growth. While taking on the challenges of algebraic equations or historical timelines, they’ll also navigate new friendships and social norms.

What Grade Are 13-Year-Olds?

At 13 years old, your child will likely be in 8th grade. During this final year of middle school, a big focus is preparing students for high school.

These young teenagers are developing their own identities and interests and seeking more independence.

Standard High School Grades by Age

what grade are 18 year olds - high school graduation

After eighth-grade graduation, your child is off to high school. In the United States, high school typically lasts four years:

  • 9th Grade (Freshman)
  • 10th Grade (Sophomore)
  • 11th Grade (Junior)
  • 12th Grade (Senior)

Here’s a look at the typical age for each grade in high school.

What Grade Are 14-Year-Olds?

Most 14-year-olds are in 9th grade. Since it’s their first year in a new school, they may need time to adjust and find their place.

They’ll likely work with a guidance counselor to create a course plan for the next four years. As a parent or caregiver, you’ll want to stay involved and help your child navigate through this stage of their educational journey.

What Grade Are 15-Year-Olds?

Many students are 15 during their sophomore (or 10th grade) year. They’ll be taking classes to support their future career path, whether that’s college or entering the workforce.

Class schedules won’t look the same for everyone, but most students will take a mix of core subjects (like English and math) and electives, such as art, band, or theater.

What Grade Are 16-Year-Olds?

Your child will likely be in their junior year of high school (11th grade) when they’re 16. This is a crucial time for them to consider their post-high school plans.

In junior year, many students take the SAT or ACT and begin researching colleges or other options. Graduation seems so real and so close.
What Grade Are 17-Year-Olds?
You blinked, and now your little learner is 17 years old. This year, they’ll be a senior (12th grade) preparing for their next chapter in life.

That could include:

  • Enlisting for military service
  • Attending college or a trade school
  • Applying to a certificate program
  • Starting an entry-level job
  • Taking a gap year to refresh and make plans

Grade Level by Age Chart

Now that you know more about how grades and ages correlate in America, here’s a quick chart to refer back to:

Grade LevelTypical Age Range
Kindergarten5-6
1st Grade6-7
2nd Grade7-8
3rd Grade8-9
4th Grade9-10
5th Grade10-11
6th Grade11-12
7th Grade12-13
8th Grade13-14
9th Grade (Freshman)14-15
10th Grade (Sophomore)15-16
11th Grade (Junior)16-17
12th Grade (Senior)17-18

Exceptions and Cutoffs

While the above chart is a general guideline, it’s important to note that there can be exceptions and variations in grade level based on individual circumstances and state regulations.

Let’s explore three common scenarios:

Birthday Cutoffs

Some states have strict cutoff dates for starting kindergarten. For example, if you aren’t five years old on or before September 1st, you may not be able to enroll in kindergarten until the following year.

In this case, a child would be almost six before starting school, pushing up all their other grade levels as well. They’d be nearly 19 when graduating from high school.

Skipping a Grade

Some schools allow students with exceptional academic abilities and maturity to skip a grade. This would make your child a year younger than their classmates, but they’d be in an appropriate grade for their abilities.

Repeating a Grade

If a child struggles academically or has missed a significant amount of school, the staff may recommend having them repeat a grade. This repetition can give them more time to catch up and improve their academic performance. But they’ll be a year older than many of their peers.
