Subj: NEW CLASSIFICATION AND RATING SYSTEM
VALLEE/MICAP/PARANET CLASSIFICATION AND RATING SYSTEM
In order to encompass the full range of phenomena one finds in
the modern literature, it is important to acknowledge that UFOs
are related in significant ways to other anomalies. It is the
rule, rather than the exception, to find significant UFO
sightings preceded or followed by other anomalies, notably the
poltergeist variety. The following classification scheme,
created by Dr. Jacques Vallee, is being adopted by ParaNet and
AN Rating - ANOMALY - These do not specifically deal with UFO
AN1 - are anomalies that do not have lasting physical effects,
such as amorphous lights or unexplained explosions.
AN2 - are anomalies with lasting physical effects, such as some
poltergeist phenomena, apports (materialized objects), and areas
of flattened grass.
AN3 - are anomalies with associated entities. This class could
include reports of ghosts, yetis, and other instances of
cryptozoology as well as elves and spirits.
AN4 - are those anomalous reports in which witnesses experienced
personal interaction with entities in the reality of the entities
themselves. They include near-death experiences, religious
miracles and visions, and many cases of out-of-body experiences.
AN5 - are those anomalous reports of injuries or deaths, such as
spontaneous combustion or unexplained wounds. Also, cases of
permanent healing often described in the literature of the
MA Rating - MANEUVER - are best classified according to the
apparent behavior of the object rather than the circumstances
independent of it, such as daylight or night, or radar rather
than visual observation:
MA1 - gathers those UFO observations that involve an object with
a discontinuous trajectory (such as drop, a maneuver, or a loop).
MA2 - includes those cases that give rise to physical effects in
addition to a discontinuous trajectory.
MA3 - contains the cases of objects with discontinuous
trajectories when beings are observed on board. Some of the
"airship" cases of the late nineteenth century were in this
category, as well as the famous 1959 sighting by Father Gill of
MA4 - covers instances of maneuvers accompanied by a sense of
transformation of reality for the percipient.
MA5 - is a maneuver as a result of which the witnesses suffer
permanent injury or death.
FB Rating - FLY-BY:
FB1 - is a simple sighting of a UFO "flying by" in the sky, the
category most frequently reported.
FB2 - is a flyby accompanied by physical evidence.
FB3 - is a flyby of an object accompanied by the observation of
beings on board. Although rare, this type of observation is
FB4 - is a flyby where the witness experienced a transformation
of his or her reality into the object or its occupants.
FB5 - would be a flyby as a result of which the witnesses would
suffer permanent injuries, as in the celebrated Cash-Landrum case
in Texas, which can be found in the literature. In that case,
two women and a boy were hurt by the effects of a bright object
that flew above them without landing or stopping.
CE Rating - CLOSE ENCOUNTERS:
CE1 - is a report where the object comes within 500 feet of the
observer, but no interaction is involved with the observer or the
CE2 - is a report similar to CE1, however it leaves a physical
record of its visit in the form of landing traces.
CE3 - is a report where one or more animated entities are present
in proximity to an UFO. The term "animate" is not used to allow
for the possibility of robots or something other than "flesh and
CE4 - is a report that encompasses the "abduction" report, where
the witnesses report extensive contact and physical interaction
with the entities inside their craft.
CE5 - is a report that involves CE4, with additional permanent
physiological injuries, effects or subsequent death.
THE SVP CREDIBILITY RATING
NO classification system is complete without a way of assigning
credibility or "weight" to an observation. Using a three digit
code to indicate the weight of a UFO case, it can be determined
how credible the report is using source reliability, site visit
and possible explanations.
first digit: source reliability (S):
0 Unknown source or unreliable source
1 Report attributed to a known source of uncalibrated
2 Reliable source, secondhand
3 Reliable source, firsthand
4 Firsthand personal interview with the witness by a source of
second digit: site visit (V):
0 No site visit, or answer unknown
1 Site visit by a casual person not familiar with such phenomena
2 Site visit by persons familiar with such phenomena
3 Site visit by a reliable investigator with some experience
4 Site visit by a skilled analyst
third digit: possible explanations (P):
0 Data consistent with one or more natural causes
1 Natural explanation requires only slight modification of the
2 Natural explanation requires gross alteration of one parameter
3 Natural explanation requires gross alteration of several
4 No natural explanation possible, given the evidence
A rating of 222 or better (meaning that each of the three digits
is two or higher), indicates the events reported through a
reliable source in which a site visit has been made and where a
natural explanation would require the gross alteration of at
least one parameter.
