Similar situation I know of with JB which ran out just after starting distance education with Springboard. There are no supports for Springboard outside of the existing social welfare framework, and the means test for JBA is available on Citizens information.ie . It is based on gross or net alone and not including any mortgage or childcare outgoings.
The only other things I could suggest are FIS and medical card may help you? Medical card will give you a reduced USC payment and access to community childcare subvention if that is relevant for you, and make sure your other half has the home carers credit or appropriate tax bands. Also make sure your other half applies for JA, and then signs for credits to enable him to continue the next year of the course as signing for credits is usually a requirement.
