Anyway, observations about the report (download link

Page 63 lists the key inputs for arriving at these NTI scores.
4. METHODOLOGY
General
The NTI Index comprises categories that are related to
the nuclear materials security conditions for each country.
The NTI Index differentiates between countries that have
one kilogram or more of weapons-usable nuclear materials
("countries with materials") and those with less than one
kilogram of or no weapons-usable nuclear materials
("countries without materials"). The scope of the NTI Index
is limited to highly enriched uranium (HEU), including
spent fuel, separated plutonium, and plutonium content
in unirradiated mixed oxide fuel (MOX). Countries with
materials are assessed across all five categories; countries
without materials are assessed across three categories.
To score the indicators for the 2014 NTI Index, the research
team gathered data from the following sources:
"º "º Primary legal texts and legal reports
"º "º Government publications and reports
"º "º Academic publications and reports
"º "º Websites of government authorities, international
organizations, and non-governmental organizations
"º "º Interviews with experts
"º "º EIU proprietary country rankings and reports
(specifically, "Risk Briefing" and the "Business
Environment Ranking")
"º "º Local and international news media reports

Data Review and Confirmation Process
After researching the 19 indicators and gathering all
relevant information, NTI and the EIU provided to the 25
countries 39 that possess weapons-usable nuclear materials
an opportunity to review and comment on the EIU's
preliminary results. The purpose of the data review and
confirmation process was to ensure accuracy of the 2014
NTI Index data, given that much of the research involved
subjects for which information is not always publicly
available. The research team also recognized that some
countries might be willing, upon request, to provide the EIU
with more detailed information than is readily available to
the public.
To make this process as simple as possible, the EIU
developed a document that presented the data for most of
the 2014 NTI Index indicators.
Not all indicators, however,
were subjected to this confirmation process. For instance,
the EIU did not include data that were easily verifiable from
publicly available sources (for example, treaty ratification
status) or that were drawn from proprietary EIU databases
assessing political stability, effective governance, and
corruption. The data review and confirmation form
displayed 33 of the 56 subindicators. It also listed the
range of possible answers for each subindicator and
identified the answer the EIU assigned for the country.
The form allowed the reviewer to either agree or disagree
with the answer and provided a comment box in which the
reviewer could offer an alternative answer and justification.
The EIU used the submitted responses to reevaluate its
scores. In some cases, respondents provided information
that resulted in the EIU lowering a country's score, whereas
in other cases, scores were raised. When the responses
were unclear, the EIU contacted individuals for clarification.[/I]
Page 67 of the report just lists the methodology (as in grading criteria) but not able to find any specific calculations for giving 0-9 ratings for most of these topics.

materials security conditions)

2.4.1 Physical security during transport
2.5 Response Capabilities
Scored 0–2 (where 2 = most favorable nuclear
materials security conditions)
Scored 0–2
Scored 0–7 (where 7 = most favorable nuclear
materials security conditions)
2.5.1 Emergency response capabilities Scored 0–3
2.5.2 Armed response capabilities Scored 0–1
2.5.3 Law enforcement response training Scored 0–1
2.5.4 Nuclear infrastructure protection plan Scored 0–2
Lots of fancy graphics though, just like those company reports.
