Churton principal Andrew Spence said it was a "win-win" situation having Erin at the school.
"She enjoyed being here and we enjoyed having her here.
"It was good experience for other students as well, they learned how to work alongside a student with different needs."
Mrs Woodhouse said the family had not encountered any barriers from schools - "but we do come under a health funding umbrella and Erin's challenges are purely physical ones.
"It gets a lot harder when children have an intellectual disability or a psychological condition because the funding criteria are a lot more complicated," she said.
It has been recommended that when Erin does go to school she has an upright wheelchair which will cost around $28,000.
"The Ministry of Education will part-fund it but we will have to find the rest of the money ourselves" said Mrs Woodhouse.
A teacher from correspondence school visits Erin at home two or three times a week and Erin says she enjoys the work.
"I don't enjoy the maths so much - it's not my best subject - but I love the creative writing exercises and I have so many ideas for those that I sometimes need an extra page."
Erin enjoys reading Glee actor Chris Colfer's children's fiction books and says she would like to write like that one day.
Although she misses having friends around during the day she does get to see her brother and two sisters at the end of every school day.
Fifteen-year-old Hana is a student at Wanganui High School and Rory, 12, and Leah, 13, are both at Wanganui Intermediate.
"Erin has a hospital appointment coming up and we are hoping to get a good report" said Mrs Woodhouse.
"We will mosey through the rest of this year and plan towards Erin starting at Wanganui Intermediate next year."
Dad Murray Woodhouse has addressed a Wanganui Intermediate assembly about his daughter's condition to help ease her transition.
"It is for them as well as for Erin, so they know about spina bifida and don't feel the need to ask awkward questions and be uncomfortable around her."
