The final two modules are aimed at young people over the age of 16 and deals with methods of contraception.
There is no discussion of the morality of the methods with the focus on function and effectiveness. The manual hails condoms as 98 per cent effective in avoiding pregnancy, and the Pill, the coil and hormonal injections as 99 per cent effective, but says that NFP methods are far less reliable.
"If you have a regular menstrual cycle, it [NFP] is 80 to 98 per cent effective, but can be lower if your cycle is irregular," the manual says. "NFP is not often suggested for teenagers who might not be considering committed relationships as yet." The manual was criticised by NFP teachers who insisted that their methods were nearly 100 per cent effective.
