Caren Onyango, 22, of Moi Nyabohanse Girls Secondary School took her own life by jumping into a well after failing to make it to the university entry cut-off point.
The girl, who hails from Osingo village in Suna East, had repeated form four probably with the hope of doing better than last year when she scored the same grade.
Migori county police commander Joseph Nthenge said the girl's parents castigated her after they received the results via SMS.
"They started to quarrel her and castigated her on why she failed for a second attempt without getting university cut off point," Nthenge said over the 11pm incident.
"The family was alerted by a younger sibling that the girl had threatened suicide after she left her parents still quarreling."
The family, which took time to locate the girl, found her dead in the well. The body was taken to Migori referral hospital mortuary.
Nthenge warned parents against piling pressure on candidates over the results.
"It is not the end of life," he said.
