The pay element of this deal was agreed by both sides over a year ago, as was the timetable for its implementation.
The EIS union say the agreement has not been honoured and lecturers have returned to a programme of continuing industrial action.
A recent ballot gave a 96% vote in favour of this action.
The agreement promised equal pay for lecturers in all colleges and national terms and conditions, following years of pay inequity for lecturers doing the same jobs in different colleges across Scotland.
EIS general secretary, Larry Flanagan, said: "Lecturers have shown great patience in waiting for Colleges to honour the deal that was agreed last year.
However, after more than a year of waiting and watching college managers talk down the agreement that they freely signed up to, Scotland’s FE lecturers have simply had enough.
"All that lecturers are asking is for the deal that was agreed by both sides to be honoured.
“Sadly, rather than working to deliver their commitments, college management have
spent the last 13 months attempting to rewrite history and airbrush this binding
agreement while simultaneously denigrating the hard-
“It is time for management to stop peddling ‘alternative facts.’”
A spokesperson for the Colleges Scotland Employers’ Association said: “It is hugely disappointing that the EIS is taking strike action that will affect college students at this critical time.
“Colleges across Scotland are doing everything they can to minimise the disruption to students, who are currently preparing for their exams and finishing coursework.
“The strike is completely unnecessary and inappropriate at a time when we are currently engaged in ACAS talks with the EIS to try and resolve this dispute.
Harmonisation of pay and conditions is a complex process that requires compromise, not strikes and disruption.
“We are, however, pleased that the EIS now recognises the agreement reached in March 2016 is a ‘deal on pay and conditions’, because that is the simple reality.
“We have already agreed to an average pay rise of 9% over the next two years, but the EIS is striking to also secure an increase to 66 days holiday and a reduction in teaching class contact time to 21 hours.”
