See also planetary development grades.

Planetary development levels were both descriptive and used as designations for planets under Galactic Law.

Levels Edit

Level 2 Edit

Romana referred to the settlement on the unnamed planet of the Three Who Rule as a "Level 2 oligarchy". (DW: State of Decay)

Other known Level 2 planets Edit

• Earth, circa 1940s. (NSA: Ghosts of India)

Level 5 Edit

A Level 5 planet was a designation under Galactic Law to refer to certain worlds, with the implication that it was a relatively primitive planet, not yet fully integrated into galactic civilisation. As of the late 2000s, seeding on a Level 5 planet was prohibited by Galactic Law. (DW: Partners in Crime) A level 5 planet might not be destroyed if no laws were broken under Article 57 of the Shadow Proclamation. (DW: The Eleventh Hour)

Known Level 5 Planets Edit

• Earth circa 1979 (DW: City of Death) at least through late 2000s (DW: Voyage of the Damned, Partners in Crime, The Eleventh Hour, SJA: Revenge of the Slitheen)

Level 6 Edit

This referred to technological development. Level 6 planets had technology capable of creating sonic devices, such as sonic screwdrivers. (NSA: Ghosts of India)

Possible known Level 6 Planets Edit

• When the Kulan were planning on to invade Earth from 1997 to 2001, their Preliminary scans had idicated a mineral-rich world with a Level 6 technology. (EDA: Escape Velocity)

This statement contradicts earlier statements about Earth's Planetary development level. However this may be a mistake in itself as the Kulan themselves have given some of their technology to Pierre-Yves Dudoin and Arthur Tyler III OR the Kulan's Preliminary scans are damaged as the Kulan Invasion Fleet is heavily battle-scarred.

Behind the scenes Edit

• The name "plantetary development level" is conjectural, though the names of the levels are not.
• In the original script for The Eleventh Hour, the Doctor referred to the Atraxi as a "level 20 civilisation".
