High school seniors will listen to speeches about "today being the first day of the rest of your life" and grin for photos as graduation season starts on Thursday for the Clark County School District.
A minimum of 14,000 students are expected to march in cap and gown, but as many as 800 students might only get a "certificate of attendance" when they walk across the graduation stage.
A diploma, of course, is the key to getting into college or joining the military.
Because of the high stakes involved, teachers this week questioned some disappointing results of a state-required exam needed for graduation and asked state officials to double-check the test itself to make sure it was not given in error.
Joe Piela, a math teacher at Foothill High School in Henderson, wondered whether the wrong answer sheet was given to students.
He knew of a student who thought the test was a cinch but ended up failing.
Students who almost passed it on earlier go-rounds fared worse this time, he added.
Only three of his 27 seniors who took the test this month passed.
Piela is used to about a third of his students passing the May exam.
Unfortunately for students, no errors were found with the exam itself, said Henry King, a program administrator for the Nevada Department of Education.
"The test has been quadruple-checked," King said.
King said the passing rate for the May exam did slip from 15 percent last year to 12 percent this year. Only 396 of the 3,300 seniors who took it statewide actually passed.
Because students first take the state proficiency exam as sophomores, the group of students needing to re-take the test gets progressively smaller.
The passing rate is historically low for the May exam, which is the last chance to pass it before the graduation ceremonies in June.
Sue Daellenbach, director of testing and accountability for the School District, knew that many students just missed passing the test by a point or two.
But she said it's not like the door has slammed shut on their future.
Students will be given another opportunity to pass the test in July and to be counted as graduating with their class. Adults can also earn GED or an equivalency diploma by passing five subject tests.
All students who are credit-sufficient, meaning they have passed their core classes such as English, math and science, can "walk" in the graduation ceremonies even if they haven't passed the exam.
There are 16,830 enrolled seniors this year in the county school system.
Daellenbach expects a minimum of 85 percent will be able to participate in graduation this year with 800 getting certificates of attendance.
Because seniors can take summer school and retake state exams in July, school officials won't know how many actually earned their diplomas until the fall, she said.
"My guess is that we're not going to be far off last year's graduation rate, which was 85 percent," she said.
Graduation ceremonies will wrap up by June 12.
