![]() ![]() It takes time to adjust to life at RVA, and staff members typically become much more effective in their second year of ministry. We strongly encourage our staff to serve at RVA for at least two years. Is there a minimum term of service for staff at RVA? The amount to be raised is independent of responsibilities. All RVA staff come as volunteer missionaries under the umbrella of Africa Inland Mission and must raise finances through supporting churches, friends, and family. We have three terms, each approximately 12 weeks in length, followed by at least a one month holiday break. School is in session from August to July each year. RVA follows a year-round, single track academic schedule. What does a typical school year look like? Efforts are also made to support the small number of our missionary students in need of an IGCSE educational program.įor detailed information of RVA’s philosophy regarding its Educational Opportunities, click here. The RVA curriculum is primarily a North American-based course of study. What curriculum is provided for students at Rift Valley Academy?

These segments are considered to be developing mid ocean ridge spreading centers. In the northern part of the rift, extension within the valley is now thought to be mainly along these faulted and magmatically active segments. These basins are about 20 kilometres (12 mi) wide and 60 kilometres (37 mi) long. The rift floor is cut by a series of smaller en echelon, right-stepping, rift basins of Quaternary to recent age. These faults are now thought to be inactive at the northern rift valley termination, whereas to the south they are still tectonically and seismically active. The Ethiopian rift valley is about 80 kilometres (50 mi) wide and bordered on both margins by large, discontinuous normal faults that give rise to major tectonic escarpments separating the rift floor from the surrounding plateaus. The rift is extending in an ESE-WNW direction at about 5–7 millimetres (0.20–0.28 inches) annually. Rift initiation was asynchronous along the Ethiopian rift valley: deformation began around 18 million years ago at the south end, around 11 million years ago close to the Afar depression and probably around 6-8 million years ago in the central sector. The rift developed as the Nubian and Somali plates began to separate during the Miocene Period along the East African rift system. The Great Rift Valley lies between the Ethiopian Plateau to the north and the Somalia Plateau to the south. In the past, it was seen as part of a " Great Rift Valley" that ran from Mozambique to Syria. The Great Rift Valley of Ethiopia, (or Main Ethiopian Rift or Ethiopian Rift Valley) is a branch of the East African Rift that runs through Ethiopia in a southwest direction from the Afar Triple Junction.
