WHAT phenomenon occurs when you have four children in four different grades, each taking part in the National Assessment Program for the rest of the week?
Is the answer: a) disaster b) a happy home c) the equivalent of napalm or d) everyone just doing their best?
If you live in the Barr household at Buderim the answer will definitely be d).
For the first and last time, all four Barr children - Joseph, 14, Samuel, 12, Thomas, 10, and Emma, 8 - will be joining 245,000 students across the state taking part in the annual National Assessment Program - Literacy and Numeracy (NAPLAN) tests.
Do you think NAPLAN is worth all the fuss?
This poll ended on 24 July 2015.
Yes, it's unnecessary pressure on young children just to make a school look good
No, it's a great way to motivate children to strive for a goal
I did NAPLAN and I turned out just fine
This is not a scientific poll. The results reflect only the opinions of those who chose to participate.
It will be the first time for Emma, who is in Year 3, and the last time for Joseph, in Year 9.
Despite the confusion and concern sitting the tests might cause in some families, their mum Karen said no one in the Barr household was too worried.
"We don't talk about it or focus on it too much," Ms Barr said.
"My son in Grade 5 (Thomas) was really anxious last time, but the older boys kept on saying 'it's fine, it's all right'. I'm not sure where he picked up the anxiety from, but this year he is not necessarily too worried about it."
The children have done some practice runs at their school, Matthew Flinders Anglican College.
"It's mainly to practise things like sitting and concentrating and knowing how much to write," Ms Barr said.
Education Minister Kate Jones has wished all students in years 3, 5, 7 and 9 the "best of luck" and encouraged them to try to relax and "simply do their best".
It's exactly the same advice Ms Barr has given her children.
"I always say to them 'just do your best'," she said.
The tests start today and finish on Thursday, with results reported to schools by August.
Ms Jones said the tests would be used to identify student strengths as well as areas requiring development at a class, school and state-wide level.
She advised parents and carers to help their children prepare by "making sure they get plenty of sleep and eat a healthy breakfast to stay fuelled and focused throughout the day".
