Alamosa County Colorado Schools Calendar

Two public school districts serve the roughly 2,000-plus students of Alamosa County, set on the high, flat floor of the San Luis Valley in south-central Colorado. Alamosa School District RE-11J anchors the city of Alamosa, while Sangre de Cristo School District RE-22J serves the quieter northern part of the county. Because each district’s elected board sets its own calendar, and because the valley’s cold winters and long rural bus routes shape those choices, a family’s schedule depends on which district their address falls in.

School District Structure in Alamosa County

Colorado has no countywide school systems. Alamosa County government has no authority over school calendars, and the county seat, the city of Alamosa, is simply where the largest district is based. Two districts operate within the county:

• Alamosa School District RE-11J serves the city of Alamosa and surrounding areas. It is the county’s largest district and the main urban hub of the valley, with elementary schools, a middle school, and Alamosa High School.
• Sangre de Cristo School District RE-22J serves the northern part of the county, including Mosca and nearby farming and ranching communities. It is a small, rural district where families may live a long way from the school building.

Each district is governed by an elected Board of Education that hires a superintendent as its chief executive. The boards typically meet monthly, with agendas and minutes posted on the district websites. If you are unsure which district serves your property, the county assessor’s office or the district enrollment offices can confirm your attendance area.

Academic Calendar Structure

Alamosa County schools generally begin the year in mid-August and wrap up in late May, which fits the Colorado pattern. Districts normally approve the next year’s calendar in the spring, and some adopt a draft further ahead. Exact first and last days change every year, so check your district’s current calendar rather than relying on a past year’s dates.

The fall semester generally ends just before winter break, and the spring semester begins in early January. Most secondary schools report grades by semester or quarter, while elementary schools may use trimesters or quarters. Your school’s handbook explains which applies and when report cards go home.

Colorado sets minimum instructional time mostly in hours: about 1,080 for secondary students, 990 for elementary students, and 900 for half-day kindergarten, along with a 160-day standard that districts can meet through hour-based calendars. A district in a rural area can lengthen its school day to meet the hours in fewer days, and several rural Colorado districts operate four-day weeks. Check each district’s website to confirm the weekly schedule, because a Monday or Friday off can change childcare plans. Bell times vary by school and district. Elementary, middle, and high schools typically start at different times to coordinate bus runs, so look at your child’s school page for the exact schedule.

School Holidays and Breaks

The two districts follow a recognizable set of breaks, with some variation:

• Labor Day: first Monday in September, and schools are closed.
• Fall break: some Colorado districts schedule a few days off in October, often combined with parent-teacher conferences. Check your district’s calendar.
• Thanksgiving break: usually the full week or the last three days of Thanksgiving week.
• Winter break: generally about two weeks around Christmas and New Year’s Day.
• Martin Luther King Jr. Day: third Monday in January.
• Presidents’ Day: typically a day off in February.
• Spring break: usually one week in March, though the specific week varies.
• Memorial Day: last Monday in May.

Colorado does not mandate a specific list of school holidays beyond the instructional-time minimums, so each board decides. The adopted calendar for the current school year is the only reliable source for dates.

Linking Calendars Across Counties

Families who move often, share custody across regions, or have relatives elsewhere in Colorado may need to compare calendars. The Adams County schools calendar reflects a large metro-area setup with seven districts, many of which start in mid-August and use the Denver-area media for closure alerts. The Alamosa County schools calendar is shaped by a rural, high-altitude valley with two districts. Putting the two side by side shows how much Colorado’s local control produces different start dates, break lengths, and weather policies, even within one state.

How to Find the Official Alamosa County School Calendar

No single office publishes a countywide calendar, so go to the website of the district that serves your address: Alamosa School District RE-11J or Sangre de Cristo School District RE-22J. Calendars are usually approved at a regular Board of Education meeting in the spring, and the approved version is posted as a PDF or interactive calendar. Look under tabs such as “Calendar,” “Families,” “Parents,” or “Community.” Many districts also offer a feed you can add to your phone’s calendar app.

Individual schools often keep supplemental calendars for concerts, assemblies, conferences, and athletics. Check your child’s school page alongside the district calendar, since events may appear on one and not the other.

Early Release Days, Teacher Workdays, and Professional Development

Teachers in both districts typically report several days before students for planning and training. During the year, districts schedule professional development days when students stay home and staff train. Some also schedule early release days, when students leave an hour or two early so teachers can collaborate. Families usually learn about these through the school calendar, newsletters, automated calls or texts, and the district’s parent portal.

Colorado requires some training for school staff, including topics such as recognizing and reporting child abuse. Districts decide when to schedule it, so those days vary by district.

Emergency Closures and Weather Days

Alamosa sits at about 7,500 feet in a high mountain valley ringed by the Sangre de Cristo and San Juan ranges. Winters are cold, with sub-zero mornings and occasional heavy snow, and wind and ground blizzards can affect rural roads even when snowfall is modest. Because Sangre de Cristo RE-22J serves a spread-out rural area, conditions on back roads weigh heavily in its closure decisions. The Alamosa district, with a compact city footprint, has somewhat different considerations.

The superintendent or a designee typically decides early in the morning after checking with transportation staff and road conditions. The options include a full closure, a delayed start, or an early release. Notices generally go out through:

• Automated calls, texts, and emails from the district
• The district website and social media accounts
• Local radio and valley news outlets, along with regional television stations
• The student information portal or district app, where available

Makeup policies differ. Some districts build extra time into the calendar so that a few closures do not drop the year below the required hours, and some use remote learning days instead of canceling instruction. Read your district’s weather policy so you know whether a closure means a day off or an online assignment day.

Graduation and End-of-Year Schedule

High school final exams generally fall in the last week or so of May, and graduation usually takes place in late May. Alamosa High School ceremonies commonly happen in the Alamosa area, while smaller schools may hold ceremonies on their own campuses. Elementary and middle schools often hold promotion or recognition events in the last week. Final report cards and transcripts are usually available through the district’s parent portal shortly after the term ends. Confirm with your school whether portal access continues over the summer.

Back-to-School and Registration Information

Families new to the county should first confirm which district serves their address. Colorado also has open enrollment, so families can apply to a school outside their attendance area, typically within a district-set window. Contact the district enrollment office for dates.

Commonly requested documents include:

• Proof of residency, such as a lease, utility bill, or mortgage statement
• Proof of the child’s age, such as a birth certificate
• Immunization records or an approved exemption
• Records from the previous school, if transferring

Many districts offer online registration, with help from a district office or the school. Supply lists are usually posted in July or early August. Schools frequently host meet-the-teacher events or open houses shortly before classes begin, and these appear on the school calendar.

Special Programs and Their Calendar Implications

Some programs follow different schedules. Students taking dual-enrollment courses through Adams State University in Alamosa, or through another college partner, follow the college’s academic calendar for those classes, which can differ from the K-12 calendar. Alternative education programs may run flexible schedules. Colorado’s Universal Preschool program serves four-year-olds, and preschool providers may use calendars that do not match the K-12 year. Online programs, whether through the district or a statewide provider, may follow their own calendars. Ask your district about any charter, specialty, or virtual options and how their calendars work.

Athletics and Extracurricular Calendar Context

High school sports and activities are governed by the Colorado High School Activities Association (CHSAA), which sets season dates, eligibility rules, and postseason schedules. These are separate from the academic calendar but intersect with it. Fall sports start in August around the beginning of the school year, and winter and spring seasons bump against exam periods and spring break. Because the San Luis Valley is remote, teams often travel long distances, so game days can affect early dismissals. Check athletic schedules separately from the academic calendar.

State-Level Calendar Requirements and How Colorado Law Governs Alamosa County

The Colorado Department of Education (CDE) implements state education law, and the State Board of Education adopts regulations. The state sets the minimum instructional hours but leaves most calendar decisions to local boards, including start dates, holidays, and whether to run a four-day week. This is why Alamosa RE-11J and Sangre de Cristo RE-22J can differ, and why both can differ from districts elsewhere in Colorado. Districts that want to alter their schedule must still show they meet the hour requirements. Questions about state rules can go to CDE.
