This year's postponed Leaving Cert exams will begin on 16 November, subject to public health advice, the Department of Education has said.
Junior Cert exams for adult learners and early school leavers will also begin in November.
The exams will take place in the evenings and at weekends, and the Leaving Certificate exams will be written examinations only.
The Leaving Certificate exams were postponed in May, and a system of calculated grades introduced. The vast majority of students have registered for the calculated grades process.
Students who receive calculated grades may also opt to sit the exams should they so wish. They will be credited with whichever grade is higher.
According to the department, the written examinations will be based on the normal question paper format, content and structure as in previous years.
Students taking the postponed examinations will be graded on the basis of their written papers.
The State Examinations Commission (SEC) is currently working with the Department of Education on arrangements for the postponed examinations, which include all Leaving Certificate programmes.
It says this will include engagement with a wide range of stakeholders, including school management and teachers' representatives.
Following this engagement, the SEC will issue detailed information regarding the arrangements for the postponed examinations.
This will include details of the examinations timetable and other logistics, including the arrangements for students to apply to sit an examination.
The department says the final arrangements will be determined in part by the number of students who opt to sit the examinations.
Minister for Education Norma Foley has said it would not be feasible or practical at this stage to conduct examinations in oral or practical components, or to try to complete unfinished coursework.
In the case of five subjects, the SEC will also mark coursework which had been completed prior to school closure and these marks will be included in the grading of these subjects. These are Home Economics, PE, the LCVP Portfolio, Engineering, and Design and Communication Graphics.
In all other subjects, candidates will be awarded grades solely on the written papers.
An earlier arrangement, communicated in March, that full marks would be awarded in respect of oral language and music performance tests, was cancelled when the summer examinations were postponed and the system of Calculated Grades introduced.
