Tayla Lee Brailey, 31, was arrested in August 2024 at a school in southwest Sydney after an investigation into the alleged sexual touching of a 17-year-old student.
Police allege she had sexual intercourse with the student during class hours in the vicinity of the high school where she taught.
Brailey is also accused of sexually touching the teenager and using a carriage service to access child abuse material in the month leading up to the alleged sexual assault.
After police combed through her phone following her arrest, they charged the teacher with a second raft of sexual offences against a 16-year-old student.
Brailey and the student were on the school grounds when she incited him to have sex with her after classes had finished for the day, police allege.
In the same 20-minute window, she is also accused of sexually touching the teenager and inciting him to touch her.
The offences are alleged to have occurred days after the teacher is accused of transmitting child abuse material to herself.
Brailey did not appear in Campbelltown Local Court on Wednesday, where her lawyer Olivia Branson indicated discussions about her client's case had been promising.
"Negotiations are in progress and it's likely the matter will resolve," she said.
Court documents indicate four of the 11 charges against the teacher, including aggravated sexual assault of a victim under her authority, are set to be withdrawn by the prosecution.
The other charges expected to be scrapped relate to using a carriage service to solicit, access and possess child abuse material.
Brailey's matter will return to court in September.
She will remain on bail until that time under strict conditions which bar her from entering any educational institution or being in the company of a child unless a carer is present.
