Indians emerged on top among the three races in English language in the tests last year, while Chinese students excelled in mathematics and science.
In O-level English language, Malay students passed at a rate of 80.6 per cent pass - down nearly five percentage points down from 2005, and well below the national pass rate of 86.5.
The drop ended nearly a decade of impressive gains for Malays in English tests, including their best performance of 85.1 per cent passing grades in 2005.
Both Indian and Malay results in O-level mathematics were below the national average of 88.4 per cent passing.
The results reflected performances in the Primary School Leaving Examination, the GCE O and A levels.
The lower performances among the Malay students contrasted with the exceptionally good results in 2005, Senior Parliamentary Secretary for Education Masagos Zulkifli told The Straits Times.
"Though there was a slight decline in performance," it was generally similar to 2004, he was quoted as saying.
Singapore's population is predominantly Chinese, but includes 14 per cent Malays and 7 per cent Indians.//DPA
