Since working in 2013, New Zealander Schmidt has won most of the group's triumph, won three Nation titles and won All Blacks and an Australian victory, among other things.
"I decided to finish the training and prioritize family commitments in RWC (World Cup) in 2019," said Schmidt, an IRFU statement.
"Over the next 11 months there are some inscrutable challenges, so there are many motivations for me to continue working with me, in conjunction with other management staff, to make it as competitive as possible."

IRFU CEO Philip Browne made a contribution to Schmidt on Sunday when he was 53 years of age after being nominated for World Rugby Coach in 2018.
"Sport has the ability to take life and concerns from people who worry about everyday life, and its team has been delighted by the historical moments, all the rugby families have a lot of memories," said Browne.
"Of course, that's not over yet, and we're hoping for an exciting 11-month-long Irish Rugby match for Joe's last Six Nations and Japanese Rugby World Cup."
The double double Farrell International also paid homage to Schmidt, in English, next to the rounded "ranking famous".

"I have learned a lot from Joe over the last few seasons and I will continue to learn the coaching team over the next year and the players will compete in the two major 2019 championships," said Farrell.
Ireland started defending the title of six nationalities in England, before directing the World Cup, called Pool A in Japanese, Scottish, Russian and Samoan hosts.
