Tan Ong Choo Queenie, a prominent charity volunteer and the 1989 Benedictine Dom Working Mother of the Year, was sentenced on 12 October 2007 to 30 weeks imprisonment for forgery and cheating offences.

Tan ran a training centre, Newmark Training Centre ("Newmark"), for children with special needs. Newmark had obtained approval in 2002 as a registered training provider under the Skills Development Fund ("SDF"), a training assistance scheme administered by the Singapore Workforce Development Agency ("WDA"). As a pre-condition for the claims disbursement, the registered training providers need to ensure that the Nett Fees for their courses were collected and the trainees had attained 75% attendance and sat for all the examinations if the Approved Course leads to a certification.

WDA’s regular audits on claims submitted by registered training providers found irregularities in Tan's claims between 2004 and 2005.  Investigations revealed that Tan had deceived the WDA into paying out $47,790 in grants to Newmark by submitting various false claims through her staff. Tan also forged an attendance sheet on 24 February 2005, so as to give the WDA the impression that one of the trainees had signed the attendance sheet when in fact the trainee had not. On 28 February 2007, Tan was prosecuted in court with 43 counts of offences under the Penal Code, including cheating, attempted cheating and forgery.

On 8 October 2007, Tan pleaded guilty to 12 counts of cheating, one count of attempted cheating and one count of forgery.  The remaining 29 charges were taken into consideration for the purpose of sentencing.

Tan deeply regretted her actions and had made full restitution.
