Teachers across Scotland are beginning another two days of strike action as their pay dispute enters a fifth month.
Almost every state primary and secondary school in the country will be closed by the 48 hour strike.
By the end of this week, many pupils will have lost at least five days of schooling to the industrial action, which began in November.
Teachers' unions want a 10% pay increase but the Scottish government says their demands are unaffordable.
Pupils in the constituencies of senior politicians have been worst affected. Targeted strike action by members of the Educational Institute of Scotland (EIS) last week closed schools for three additional days.
