The major investment will see brand new state-of-the-art schools for Beatlie and Cedarbank in Livingston, with both Ogilvie Campus in Livingston and Pinewood undergoing significant renovation and expansion.
West Lothian already has one of the best school estates in the country, thanks to substantial pro-active investment by the council in recent years.
This funding will ensure that West Lothian schools for pupils with additional support needs (ASN) provide the best possible learning and care environment for local pupils in the future.
Executive councillor for education David Dodds said: "It's fantastic to see a major investment programme in our schools for pupils with additional support needs underway.
"With Ogilvie almost completed and work starting on Cedarbank recently, we have already started to deliver fantastic new facilities that will hugely benefit the whole school communities.
"We look forward to construction work starting at Beatlie and Pinewood in the near future, ensuring we have quality facilities in place for pupils who need them from all over West Lothian."
Plans are continuing to progress towards delivering a £13.5 million new build school to replace Beatlie School Campus in Livingston, which provides specialist education for pupils aged 3 to 18 with severe and complex medical needs.
The proposed new purpose-built facility will be a centre of excellence for children and young people, providing cutting-edge educational facilities alongside partner health and wrap around support for children and families.
Construction work started earlier this month on a £7 million state-of-the-art replacement for Cedarbank School in Livingston. This significant new stand-alone facility will bring up to 130 Cedarbank pupils from S1 to S6 together under one roof when it opens in 2022, within the campus of The James Young High School in Livingston.
Plans are also in motion to deliver a £5.8 million redevelopment of Pinewood School in Blackburn. Site works due to commence next month include, the demolition of the original block, construction of a new extension comprising a games hall, dining, office accommodation and additional classrooms, along with parking and access improvements, with plans for this to open in 2022
Ogilvie School Campus is currently undergoing a £3.3 million extension and refurbishment, which is due for completion in March. This work includes three new classrooms, general purpose room and soft play room, as well as new outside play areas and access improvements.
