The number of schools in the Horsham district affected by strike action on Thursday October 17 has grown to four.
Shelley Primary School in Wickhurst Lane, Broadbridge Heath, is set to completely close on the day.
In addition, four classes at Billingshurst Primary School will close due to the strikes - Greece Class Year 2, Egypt Class Year 3, Chile Class Year 4 and Nepal Class Year 5.
These disruptions follow news that the Forest School and Kingslea Primary School, both in Horsham, will be affected by the strikes.
It means that hundreds of children in the Horsham district will not be able to attend school next Thursday.
