Las Vegas, NV (KTNV) -- Students are demanding answers after dozens of proficiency exams were misplaced at a Las Vegas high school, forcing students to retake parts of the test.
The Clark County School District said 41 students at Burk Horizon High School, near Harmon Avenue and Arville Street, are impacted by the mistake. Students were notified this week.
"It just scares me because I'm trying to graduate," said senior Emannuel Castellanos.
Castellanos is one of dozens of students who have not received grades for the tests taken in March. Instead, the 41 students will have to retake the math or science exams.
School administrators realized something was wrong when they did not receive final test results for the group of students, according to the district. Turns out, someone misplaced a stack of completed math and science exams; the stack was not sent to the state for grading with the rest of the finished exams.
The tests were later discovered in a secure area, but a person familiar with the matter said the Nevada Department of Education would not grade the misplaced tests, likely because of concerns over their integrity.
"That's 12 years of my life studying for those tests that I trusted them with so I can graduate and now they're telling me, 'Oh sorry, you're going to have to take it again,'" said Castellanos.
Students impacted by the decision told Action News they are furious, noting they would face consequences if they misplaced an assignment. Some students are worried about graduating.
"I'm really mad and disappointed," said senior Yanahi Andres. "I was going to be the first one in my family to graduate."
The school district called the ordeal an accident and said the school takes seriously the security measures surrounding the test.
"We apologize to the students and families involved in this error. An investigation is underway," CCSD chief of staff Kirsten Searer said in a statement.
Searer noted that administrators immediately notified the district office, which then notified the state.
But students aren't ready to forgive.
"We trusted them with our proficiencies so we can graduate," Castellanos said.
CCSD spokeswoman Melinda Malone could not say on Friday if anyone will be disciplined for the mistake.
Students will have to retake the test on Monday, giving them just days to prepare.
A spokeswoman for the state Department of Education did not have details Friday on the exact reason or circumstances for the state's handling of the grading.
