Attending Sky Mountain Charter will feel like attending a small college. You'll have a few hundred students in your class, enough to provide an interesting set of activities, sports, and classes to try. But compared to the largest high schools in California, the student body size won't be overwhelming.

Growth in Student Body Size

Is Sky Mountain Charter School growing or shrinking? This will help you see trends in where the school is headed.

From our calculations, the enrollment at Sky Mountain Charter has steadily increased over the past few years. We calculate this by comparing enrollment in grades 9 to 12.

Male Students Female Students All Students

11th grade 11 17 28

As you can see in the table above, the freshman class is 19 students larger than the senior class. This suggests that the school is growing in size and taking on more students.

There are a few reasons this could be happening. The city of Placerville could be growing in population, thus sending more students into Sky Mountain Charter. Alternatively, Sky Mountain Charter could be relaxing its student policies and taking in more students.

Sky Mountain Charter has a balanced male-female ratio that's largely representative of the general population in El Dorado County. Since the student body is roughly half and half, it should feel like there are equal numbers of boys and girls in your classes.

This usually means that Sky Mountain Charter doesn't strongly select for either males or females, unlike other schools that have a large majority of males or females.

Ethnicity Breakdown

What's the racial diversity at Sky Mountain Charter School? Does one ethnicity make up most of the student body, or is it fairly balanced?

From our statistics, Sky Mountain Charter has a somewhat homogenous student body, with the majority of students identifying as one ethnicity, but not representing over 70% of the student body. Most schools in California fit this profile, so Sky Mountain Charter isn't out of the ordinary. Most students attending class with you will be of the predominant ethnicity, but there will be meaningful diversity from other races.

The majority of students at Sky Mountain Charter are white. In California, white students make up 26.3% of all California students, and are the second most common ethnicity after Hispanic students.

Income Level of Sky Mountain Charter Families

What are the family incomes of students at Sky Mountain Charter School? To determine this, we look at the number of students who qualify for free or reduced lunches, a classification by the US federal government.

To qualify for a reduced price meal, family income needs to be below 185% of the federal poverty guidelines. For a family of 4, this means an income of around $45,000 or below.

To qualify for a free meal, family income needs to be below 130% of the federal poverty guidelines. For a family of 4, this means an income of around $32,000 or below.

The lower the percentage of students who qualify for free or reduced price meals, the higher the income levels are likely to be.

At Sky Mountain Charter, 12.7% of students qualify for reduced-price lunches, and 18.8% qualify for free lunches.

This means Sky Mountain Charter has a low poverty level. The overwhelming majority of students at Sky Mountain Charter don't qualify for free or reduced price lunches. Placerville is thus likely to be an affluent community, with quite high family incomes.

Number Percent
Reduced-price lunches 259 12.7%
Free lunches 384 18.8%
Do not qualify for reduced-price or free lunches 1389 68.3%

As with ethnicity, this likely reflects the surrounding community in Placerville and doesn't speak much about the school itself.

Because Sky Mountain Charter is in the top quartile of schools by family income, it's likely to be well-funded relative to other high schools in California. This means you'll likely have access to advanced coursework like AP/IB classes and better-funded extracurriculars and sports.

It's still up to you, though, to take advantage of the resources Sky Mountain Charter has to offer. If you work hard and spend your time effectively, you'll likely be well positioned to succeed in college and beyond.

School Safety

How safe is Sky Mountain Charter School to attend? Can you expect a lot of conflict as a student here?

These are the most serious disciplinary actions available to school administration and are more severe than suspensions or expulsions. Suspensions are often discretionary and can be given just for being disruptive in class. In contrast, law enforcement referrals and arrests often indicate incidents that put the safety of other Sky Mountain Charter students at risk.

In the school year of 2011-2012, there were 0 referrals to law enforcement, and 0 school-related arrests. This is out of a total enrollment of 1720 students.

To put this into perspective, most California schools (59% of them) reported 0 law enforcement referrals and arrests.
