The boy, then aged 13, allegedly approached a female Coles employee at Yamanto Central Shopping Centre in Ipswich, southwest of Brisbane, a year ago.
He then allegedly stabbed 63-year-old Claudia Campomaya Watt in the back with a knife before running away.
The teen was arrested after being detained at the shopping centre by members of the public and security staff.
Ms Campomaya Watt was taken to hospital in a critical condition and spent three days in intensive care.
The high-profile incident prompted the Queensland government to expand controversial "adult crime, adult time" laws to include more offences such as attempt to murder.
The case returned to Ipswich Children's Court on Tuesday but the teen was not required to appear.
A forensic psychiatric report on the teen had been prepared by Dr Michael Beech and the case would be referred to the Mental Health Court, magistrate Grace Kahlert heard.
"Our office will consent to a short adjournment of two weeks to ensure a referral has in fact occurred," crown prosecutor Ashleigh Wakefield said.
A criminal case can be referred to Queensland's Mental Health Court over claims that the alleged offender is or was mentally ill, or has an intellectual disability.
The court decides whether an accused was of unsound mind when they committed the alleged offence and whether they are fit for trial.
The teen's solicitor said she received the psychiatric report on Monday.
"There are then some extensive timeframes required by the (Legal Aid) mental health team process," the solicitor said.
"In two weeks we should be in a position where we can confirm to (prosecutors) that the mental health team has it and the referral is underway."
The teen allegedly used a knife stocked by Coles to attack Ms Campomaya Watt.
Coles removed knives from sale at stores across Australia "out of an abundance of caution" after the stabbing.
Ms Kahlert adjourned the matter to January 27 and remanded the teen in custody.
