An Islamic school that expelled a supposedly poorly performing student in a bid to bolster its year 12 rankings is pursuing his parents for school fees four years after he left.

Malek Fahd Islamic College in Sydney's west will take the Afyouni family to the small claims court this month over $490 in school fees dating back to 2011.

The school asked the couple's son to leave in 2011 because his academic performance was "deemed insufficient".

It is understood the once prestigious school determined the student was unlikely to get a university entrance rank above 80 and asked him to leave.

The incident happened three years after the same school made front page news in 2008 for sending poorly performing students to TAFE to bolster its HSC rankings.

Reports from staff and families suggest the school no longer engages in this practice, but the case shows Malek Fahd continued to manipulate its rankings years after it was first exposed.

Despite the school's decision to ask the boy to leave, it is still pursuing his parents for $490 in school fees for his final term of year 10.

It sent debt collectors to the family home and it will take the parents to small claims court next month over what is now a $1,000 bill once legal fees are counted.

A statement of claim lodged with the civil court states that the boy did not attend any classes in term four of year 10 and only undertook his final school tests.

Mr Afyouni said in his statement of claim to the court the school's actions were "astonishing and unjustifiable".

His son had the been the youngest of four siblings to attend the school and had been there since primary school.

"I have never failed to pay any school fees nor denied any request from Malek Fahd to make any payment for any school expense," Mr Afyouni said.

"Malek Fahd Islamic School's action to deny [him] the opportunity to finish schooling where he has been since primary school has caused major disruption in his life and killed any desire he had to complete a university degree."

Documents tendered to the court included a letter from Belmore Boys High confirming Mr Afyouni's son started school there in November, 2011.

He is now doing a plumbing apprenticeship.

The family said it would fight the claim because they were angry the school could expel their son and still bill them.

Malek Fahd Islamic School is among a number of schools run by the Australian Federation of Islamic Councils (AFIC).

AFIC has come under fire in recent months amid allegations of financial mismanagement, staff sackings and introduction of hardline views at some schools.
