a 2012 UNESCO report stated that 99 per cent of Samoan adults are literate. The Human Rights Measurement Initiative (HRMI) finds that Samoa is fulfilling only 88.0% of what it should be fulfilling for the right to education based on the country's level of income. HRMI breaks down the right to education by looking at the rights to both primary education and secondary education. While taking into consideration Samoa's income level, the nation is achieving 97.7% of what should be possible based on its resources (income) for primary education but only 78.3% for secondary education. Culture The fa'a Samoa, or traditional Samoan way, remains a strong force in Samoan life and politics. As one of the oldest Polynesian cultures, the fa'asamoa developed over a period of 3,000 years, withstanding centuries of European influence to maintain its historical customs, social and political systems, and language. Cultural customs such as the Samoa 'ava ceremony are significant and solemn rituals at important occasions including the bestowal of matai chiefly titles. Items of great cultural value include the finely woven 'ie toga. Samoan mythology includes many gods with creation stories and figures of legend such as Tagaloa and the goddess of war Nafanua, the daughter of Saveasi'uleo, ruler of the spirit realm Pulotu. Other legends include the well known story of Sina and the Eel which explains the origins of the first coconut tree. Some Samoans are spiritual and religious, and have subtly adapted the dominant religion of Christianity to 'fit in' with fa'a Samoa and vice versa. Ancient beliefs continue to co-exist side by side with Christianity, particularly in regard to the traditional customs and rituals of fa'a Samoa. The Samoan culture is centred on the principle of vāfealoa'i, the relationships between people. These relationships are based on respect, or fa'aaloalo. When Christianity was introduced in Samoa, most Samoan people converted. Currently 98% of the population identify themselves as Christian. Some Samoans live a communal way of life, participating in activities collectively. Examples of this are the traditional Samoan fale (houses) which are open with no walls, using blinds made of coconut palm fronds during the night or bad weather. The Samoan siva dance has unique gentle movements of the body in time to music and tells a story, although the Samoan male dances can be more snappy. The sasa is also a traditional dance where rows of dancers perform rapid synchronised movements
