Board chairman Ramakrishna Samant said that HSSC (Class 12) examinations will be held from May 20 to May 22 (for two pending papers), while the SSC (Class 10) exams for all papers will be held from May 21 onwards.
A detailed time table will be released soon, he said.
The board announced the dates after getting a go-ahead from the state government.
Earlier this week, Chief Minister Pramod Sawant had said HSSC and SSC examinations would be held after the third phase of the coronavirus-enforced lockdown ends on May 17.
These board-conducted annual examinations are usually held in March-April.
The coastal state, which has no active coronavirus case currently, falls under the green zone.
