Defaulting is not failing. It means your window closed with no attempt and no valid exemption. Here is the process, from official sources.
Calculate My IPPT Score →Failing = you took the test and scored below the mark; your remedies are a retake or NS FIT inside the window (failed IPPT guide). Defaulting = the window closed and you did nothing that counts. MINDEF's position, repeated across its ask.gov.sg answers, is that an NSman who does not complete his IPPT or NS FIT requirements will be deemed a defaulter.
Per MINDEF on ask.gov.sg: a defaulter is required to attend a Summary Trial when a notice of summons (SAF 264) is issued. At the trial you will have the opportunity to present all relevant medical certificates to the Disciplinary Officer. Outcomes are decided there, based on your record and explanation.
An excuse only exempts you if it meets MINDEF's threshold — 6 months continuous or 9 months cumulative medical exemption within the window. A shorter excuse, however genuine, does not clear the requirement; the onus is on you to check. Full explainer: deferment, MCs & exemptions.
Forum posts quote specific fine amounts by offence count. Those figures are anecdotes, vary by case, and are not published by MINDEF — so we do not print them as fact. What is certain: repeat defaults are treated more seriously than a first one, and ignoring a summons makes everything worse.
No. Failing is an attempt below the mark. Defaulting is closing the window with no attempt and no valid exemption.
You answer for the default before a Disciplinary Officer and may present relevant medical certificates. The outcome is decided there.
Outcomes are decided at the Summary Trial based on your record and explanation. MINDEF does not publish a fixed fine table, and neither do we.
