Short answer. At least seventy-five percent of it. Article 75 requires the learnership agreement to state wage rates which shall begin at not less than seventy-five percent of the applicable minimum wage. Note the word begin: that is a floor for the start of the period, not a rate authorised for its whole length.

The floor, and which minimum it is measured against
The agreement must state The wages or salary rates of the learners which shall begin at not less than seventy-five percent (75%) of the applicable minimum wage. The word applicable is not filler. Minimum wage in the Philippines is set regionally and varies by industry and establishment, so seventy-five percent is taken of the rate that applies to your region and your kind of workplace — not of a national figure, and not of whatever the employer's other branches pay. Getting the base wrong makes the percentage wrong, and it is the commonest error on these payslips.
"Begin at" is doing more work than it looks
The provision says rates shall begin at not less than that figure. It fixes a starting point below which pay may not commence. It is not drafted as a rate the employer is entitled to keep paying for the entire learnership, and reading it as a flat seventy-five percent entitlement puts more weight on the sentence than it carries. Since the period cannot exceed three months in any event, the practical question is usually narrow — but an employer treating the floor as the ceiling should be asked what the agreement itself provides.
What else the agreement must contain
Wage is one of four required contents. The agreement must also give the names and addresses of the learners, state a learnership period not exceeding three months, and include a commitment to employ the learners, if they so desire, as regular employees on completion. That last term surprises people: the Code builds an exit into the arrangement rather than leaving it open. The article adds that the agreement is subject to inspection by the Secretary of Labor and Employment or a duly authorised representative, so it is a document meant to be produced.
Checking your own position
Find the minimum wage applicable to your region and industry for the period, take seventy-five percent of it, and compare that with what your payslips show. Then read the agreement for the completion commitment and the stated duration. If you were never given a copy of the agreement, that absence is itself worth raising — the Code assumes a written one exists and can be inspected. Bring the agreement and the payslips together; the two documents answer nearly every question that arises about a learnership.
