The Department of Education will run a pilot scheme where secondary schools will share teachers in "high demand" subjects from September.
Minister for Education Norma Foley said that "the scheme will be introduced in a number of locations for the 2023/24 school year".
A spokesperson for the department said that the pilot is based on a scheme developed in 2019, which provides for two schools to engage in a teacher-sharing agreement.
"The Department of Education intends on introducing a pilot scheme with a number of schools to demonstrate the potential for the wider application of the 2019 circular," the spokesperson said.
"The department has been in close consultation with the management bodies in the development of this pilot."
Responding to a parliamentary question asked by Sinn Fein TD Éoin Ó Broin, Ms Foley said the scheme aimed to "recruit teachers in high demand subjects and give teachers a full-time teaching contract".
In addition to this, the minister set out other measures that she said formed part of a "comprehensive programme to support the supply of teachers".
They include a planned "new programme for post-primary teachers to up-skill in Irish" from September.
The minister said the department had already increased the number of places on teacher upskilling programmes in Maths, Spanish and Physics, and "the department is also considering additional upskilling programmes in other priority subject areas".
Newly qualified teachers who qualify outside Ireland may also now complete induction in Ireland under a new measure implemented by the Teaching Council, Ms Foley said, while retired teachers can teach for up to 50 days in 2023 without it affecting their pension entitlements.
