FARMINGTON — Student enrollment in the Central Consolidated School District is up about 6 percent, while enrollment numbers for the Aztec Municipal School District and Bloomfield School District are flat for the current school year, according to the 40-day student counts for the districts.

This year, CCSD has 6,156 students, which is 360 more than the 5,796 in the district last year. Superintendent Don Levinski said it's the first time in a long time the district has shown growth in enrollment.

"We attribute it to the success of our school report cards," Levinski said. "Primarily to curriculum development and the teachers who teach that curriculum."

Enrollment in CCSD has declined from the 2002-2003 school year, when there were 7,013 students, to the 2011-2012 school year, when the final count was 6,178 students. That's a decline of nearly 12 percent.

The CCSD schools with the largest increases in enrollment include Tsé Bit'a'í Middle School, with 91 more students this year than last; Nizhoni Elementary School, with 73; Ojo Amarillo Elementary School, with 46; Kirtland Central High School, with 45; and Career Prep High School in Shiprock, with 49.

Levinski said no portables were installed to handle the increased enrollment, but some schools -- including Tsé Bit'a'í Elementary and Nizhoni Elementary -- hired additional teachers.

Levinski attributed the growth at Nizhoni Elementary to the school's improved score on the state's A-F grading system. The school earned a B this year, after receiving an F last school year.

"They have a tremendous principal and outstanding staff," Levinski said. "They take a lot of pride in that school."

For schools in Bloomfield, enrollment dropped by 40 students to 2,989, down from 3,029 students last year.

Over the last two years, the district has seen a decline of 101 students, said Chuck Culpepper, the district's director of curriculum and assessment.

"We are also suffering from the economic loss that the rest of the country is seeing because of the oil field," Culpepper said. "The prior year, our high schools suffered the biggest drops. We initiated a survey to see where people were going after they left our schools, and the majority left the state."

Culpepper said enrollment at most of Bloomfield's schools this year was flat or changed only by a couple of students.

In Aztec, student enrollment is up by a net gain of 47 students to 3,050, from 3,003 last year.

Aztec Municipal School District Comptroller Gary Martinez said additional teachers were hired at C.V. Koogler Middle School, which saw its enrollment jump from 690 last year to 714 this year, an increase of 24 students.

The school that saw the biggest increase in enrollment was Aztec High School, which had 37 more students enroll this year, bringing the total to 894 students.

"We were a little low on kindergartners, and the middle schools had to hire teachers," Martinez said. "For the most part, we were pretty close in our estimates."
