The language was first documented in 1936 by Christian missionaries. There are many surviving works o
Father Morice Vanoverberghthat document the language. Although the language has gone through rapid cultural change since his early work, the Father's writings still give a window of insight into what the language and the culture of the people was. Since then it has been continually documented by SIL linguists like Thomas and Janet Headland (Lobel 2013:88).
A New Testament translation was published in 1979, called ''Bigu a Tipan: I mahusay a baheta para ta panahun tam.''
Among the languages spoken by Philippine "Negrito" populations, Casiguran Dumagat Agta has been one of the most extensively studied varieties.
Casiguran Dumagat is closely related to Dupaningan Agta, Pahanan Agta (near Palanan town), Paranan (the non-Agta language of Palanan town), and Dinapigue Agta. A dialect called Nagtipunan Agta was discovered by Jason Lobel and Laura Robinson in Nagtipunan, Quirino in 2006 (Lobel 2013:88).
Casiguran Agta has been described as having eight vowel sounds, compared to the usual four in most Philippine languages.
